Pros: OS independent, including configuration: Pushing buttons on units configures--PC config of units not required--works with Windows/linux/unix/freebsd, etc. Security is a form of powerline security, not heavily-hacked PC-dependent type security (only shared wiring between two residences may be a problem). Seamless--seems actually to "be" ethernet. Generally, best solution, short of actual ethernet wiring, for average sized homes. (You know!--at least one room is far away from the room with the router/switch. These rooms are difficult for wireless and require a lot of expense with that--doesn't require expensive antennas, bridges, repeaters, etc. that wireless often does.) The units are on 24/7 (I'll re-config that) and certainly have lasted . They're so good that I forget them--when I recall them, I marvel! The units don't use hated block power transformers, either--they use a simple two-pronged power cord!. Units appear to be modern, sleek, and attractive.

Cons: I think it's best not to share outlets with anything else--I dedicate one complete wall plate to each unit. Certainly, one can't use these with power strips/surge protectors/UPSes--so, the nodes are unprotected and (conceivably) could be damaged by a power surges. (I live in OKC with it's violent storms, and this hasn't happened, yet.) Nodes are not wireless--each node requires a power cord and an ethernet cord for connection to a nic. Units in houses with old wiring/multiple circuit-breakers often do encounter problems. The devices become a little warm, but never hot. It seems these particular devices are being phased out--probably replacement upgrades are brewing!

Other Thoughts: People with multiple circuit-breakers reside in huge houses--they carp about the devices not working. I respond with this: I think that such networking is beyond the scope of relatively-rudimentary consumer-based networking devices (including wireless), and pros or pro-type equipment (given sufficient research and planning) likely will prove necessary--I've noted that a "hybrid" approach involving cat5e/cat6 and wireless devices is used often.

Unfortunately, when I purchased the nodes, the market still was pretty new and Newegg did not yet offer them. Colleague devices from major networking equipment firms who also cater to consumers, even now, still require Windows/XP/Vista (IE) for config. (I'm a purist who, when practical, passes on HW that's not completely functional with open-source unix-based OSes.) Sorry, Newegg! I use you when I can!

Pros: I purchased this to avoid laying CAT5 cable in my 70 year old house. Newegg and other vendor reviews were high, so I gambled and purchased a set. First off, this thing is super easy to set up. You have to read the instructions because the units need to be "synced" but the process is super-easy & fast. The system is comprised of two identical units; you configure one as a "master" and the other as a "terminal" by just flipping a switch on them. Once the units are synced, you just plug a CAT5 cable into the "master" and run it to your router. You take the "terminal" unit and plug it into any electric socket you like, and run a CAT5 cable from it to your system. I did not test/need/use this unit to move files across a local network; I just use it to sling internet. That said, I ran speed tests from numerous outlets (and floors) both with and without powerstrips, and my speed was as fast as the hard-wired desktop.

Cons: Really none I can think of.

Other Thoughts: I can only vouch for this system as a way to extend the internet. I assume it would work fine on a more sophisticated LAN, but I don't know it's limitations (in speed) in that area. It easily handles my broadband speed, however, and regardless of how much I've stressed it with running multiple streaming video, audio, and downloads simultaneously, I've never lost connection or speed. Basically, this thing seems like a suitable substitute for running CAT5 *if* your goal is to merely extend your broadband throughout your home.

Pros: Easy setup. Throughput testing at the wall.

Cons: Latency averages about 10ms, so be careful with online games. Very sensative to older power strips.

Other Thoughts: Well worth the money! Try it out in multiple locations to get the best throughput.

Pros: This is thing is awesome. I hooked one up for myself and my parents without any issues. I can move the terminal box anywhere in the house I need to and it picks up the internet fast!

Cons: None

Other Thoughts: Great Product

Pros: Arrived here 2 days after I placed my order, and I had it up and running about an hour after finishing dinner. 90% of that time entailed finding patch cables to connect my 3 remote machines to a tiny switch that I plugged into the slave unit. This was super-quick to set up, and the self-test diagnostics indicate that I'm getting about 30 Mbps actual throughput (not just overstated link speed) from the far end of my house to the cable modem and router at the other end. This just works - I am SO thrilled to finally stop depending on Wifi for this application.

Cons: None that I've come up with yet. I love the fact that I simply plug in the pair and they start communicating. If I want to add another 13 devices, it appears that it will be easy to do so. No negatives yet - and if these keep working like this, there won't be any.

Other Thoughts: I vaguely remember considering powerline devices years ago, but the early ones got such bad reviews that I stayed away. I've spent the last several years attempting to make WiFi usable in my house, having gone through the early Linksys devices, a DLink, Belkin Pre-N and most recently Netgear Pre-N. I can't believe how much money - and time - I've blown on all of that. This Panasonic powerline gear JUST WORKS. Couldn't be happier right now. Nice!

Pros: It took longer to find an extra network cable in my spare parts box than it did to read the one page instruction sheet and get it running. Simply couldn't be easier. Now I can finally put an network access point on the opposite end of the house.

Cons: None

Other Thoughts: My order was shipped from two separate locations. I paid for UPS ground, but this one arrived by 2 day air. Newegg is amazing.

Pros: If you were like me, you probably searched the Internet like mad to find out if these devices actually worked. Well I am here to tell you that they do work, and work well. The setup was so easy, my 10 year old nephew could have installed them. The speeds are great, and I am finally able to play my games on-line without the constant disconnects I got from my wireless network.

Cons: Absolutely none.

Other Thoughts: My house is new, and has a one phase panel (double breakers on each side, but one phase), and signal strength was great all over the house. Although it doesn't apply to me, I read that if you had multiple phases in your electric system that you may experience a weaker signal. I also read that if you have issues with signal strength, you can easily correct the problem by purchasing a phase coupler that easily plugs into your dryer outlet for about $30 bucks. I hope this helps come of you, and good luck. You will absolutely love these devices.

Pros: Easy set up, go where other standard powerline products can't.

Cons: Not compatible to standard powerline.

Other Thoughts: I bought this because one of my existing powerline adaptor stopped working. Surprised, it didn't play well with others. Before I returned, I tried it - Surprised, it worked better than others - a few socket didn't work well before, now it is good. I ended up bought 6 of them (3 sets).

Pros: Literally the definition of plug and play. absolutely no problems at all.

Cons: Can't think of any.

Other Thoughts: This isn't my first Ethernet over powerline product so maybe I am biased by my past pains. On two other products I have tried the configuration was painful, I would lose connection and I have to unplug plug restart every other week, spend time with technical support etc. This product is in a league of its own. without exaggeration it took me about 5 minutes to get this setup. Got base connected to router and the other end to Tivo. Devices discovered each other within seconds and everything was up and running. It's been up for over a month with no issues.

Pros: This is a great piece of gear which allowed me to get faster transfers than WiFi to a linux server and also to my XBox360 without having to buy the XBox Wifi add-on. The beauty of this is that it's just like adding an ethernet jack to your wall power outlet.

Cons: If you hate wires, this does add some additional wiring to your setup. Also you are supposed to dedicate a wall outlet to this device rather than just plug it into a power strip (because of interference), although I did try that and it worked fine for a long time.

Other Thoughts: I bought one pair of these when they first came out and was really just waiting for the price to come down before buying more. They're very clever little gadgets. I'm not sure everyone will prefer them over WiFi but the setup is a lot easier.

Pros: They work great. They allow me to connect my ethernet switches together without running ethernet wires. DHCP, UPnP, A/V streaming, everything seems to work across them. I can't even tell that I'm going across them to the other devices. I haven't done any performance tests, which would probably show a slowdown, but visually I can't tell I'm using them.

Cons: They conflict with my "phoneline over powerline" adapters. The phoneline adapters won't get a dial-tone when the ethernet adapters are plugged in. I'm going to switch my phoneline adapters to use wireless technology DualJack), since I don't have an alternate choice for my network. (This is not the fault of the ethernet adapters.)

Other Thoughts: If it wasn't for having a satalite, I like the idea of ethernet of coax adapters (made by Zyxel), but that won't work for me. I wish that wireless bridging would grow up. that would eliminate the need for these things. I also wish that my satalite receiver would use the internet instead of phonelines to do account maintenance.

Pros: Works even where other major power line bridges do not. The separate power cord makes it easy to plug into already crowded wall outlets, The Panasonic unit also seems to be more immune to poor power line conditioning and impedance problems - it works fine on 80 year old post-and-tube wiring. And a 2 meter extension cord does not effect it at all.

Cons: ALL powerline bridges are sensitive to RF noise on the power mains. Make sure the bridge modules are connected directly to the wall socket or through a heavy (16 gauge), short, dedicated extension cord. Other devices such as computers, televisions, DVD players, etc. that incorporate switching power supplies should be connected through a good RF-filtered power strip (>20dB attenuation at 20kHz and above). Also, be aware that most US homes have two phase mains feeds, with different circuits on different phases. This can cause problems if the bridge modules are on different phase circuits: a special bridge circuit (see X10 home automation products for this) is needed to connect the two phases correctly. (If the units work when the electric dryer is running and don't otherwise, this is your problem.)

Other Thoughts: I installed a pair of these in a motor home to link my EVDO router and an ethernet switch in different areas of the vehicle. Note that this motor home has a HUGE AC power inverter/isolator between the mains and the actual outlets, so there is virtually no noise from the power line on the internal circuits. However I have also used the Panasonic HD-PLC connection in a 150 year old house with 80 year old wiring, where it also works beautifully. Note that the distance between the units is also limited to about 30 meters, so getting a connection in the barn may not work. Finally, any inductor - like a power pole transformer - in line between the units blocks the signal - so no sharing with the neighbors!

Pros: Easy to install when using just one set (see cons). I have three units feeding off the master unit (connected to the router). The three units each feed an Ethernet switch supporting even more devices. I must say I'm extremely happy with this product as I can now stream music and movies (including DVD .ISO files) with no problems. My Web browsing is a notch faster than with my Netgear X102s that these replaced. The built-in diagnostics on the devices report a connection that's over 30Mbps each.

Cons: It's not very plug-and-play when connecting three or more because since they are sold as sets of two, each terminal is pre-programmed to connect to it's master. The way to work around it is to have all terminals ready and available next to the master, reset the terminals to factory settings, and pair each terminal to the master one-by-one. Once that's done, the terminals will see the master no matter where you put them. Again, if you only need one set (master and terminal), it WILL be plug-and-play.

Another annoyance is that these adapters don't like surge protectors or power strips and are recommended to be plugged straight into the wall. I'm not sure if they have built-in surge protection but perhaps they do because the Netgear X102s did.

Other Thoughts: Newegg rocks! I actually bought a PLC kit at a local retailer for $150 plus tax. When I found out that Newegg had it for $85, I returned my kit and ordered TWO kits (I needed two anyway) from Newegg for $190 including tax + shipping! Incredible savings!

Pros: Frustrated by poor to no wireless signals in your house? This resolves it! Simple setup and it just works!

Cons: *maybe* price but if you spent as much time and money as I did trying to resolve poor wireless connections to my desktop, this is cheap AND effective!

Other Thoughts: lying on a beach in Hawaii...

Pros: Easy setup. I liked the external cord.

Cons: Completely unreliable throughout most of the house, and semi-unreliable everywhere else.

Other Thoughts: I really wanted these to work so I could stream standard def content to remote TV's or PC's. My wireless works OK with a single stream but multiple streams overwhelm wireless. So I tried this. Unfortunately, even though the HD-PLC's show the maximum blue 30+ MB connected speed, they were unable to handle even a single standard definition stream from my Sage TV server. Horrible stuttering and complete lockups everywhere I tried it.

I tried all the troubleshooting tips, but these are a no go. They might be OK for light web surfing where the consistency of data flow isn't as important, but forget streaming video despite the indicated speed.

These are going back.

Pros: Easy set up and no installation CD, unlike other wireless networking companies that seem never to work without constant tweeking and rebooting.

Cons: Does receive minimal interference from other devices plugged into the same outlet.

Other Thoughts: I have these two Panasonic devices set up on opposite sides of my house. The master is located next to my PC, up in my office on the second floor in the front of my house. The second (terminal) device is located in my basement on the far side of the house...two stories down!!! Works fantastic! Have PS3 and ROKU Music Bridge networked into this device.

As always NEWEGG is the best online retailer there is...Newegg, there is no substitute.

Pros: Zero configuration.
Works perfectly
High speed
Low Latency

Cons: Very expensive.
Extra adapters are even more expensive.

Other Thoughts: I guess you get what you pay for. I love these. I will be getting an extra adapter soon. The HD PLC will form the high speed back bone that links my HTPC, main PC and my backup (aka about to die) PC.

Pros: Took me less than 5 minutes to set up. Plug the master in, then the client... test the speed (no connection, under 10mbps, under 20mbps, +30mbps). Very easy to determine if you have good connectivity before you attach your devices. Absolutely no configuration needed for my setup. I am able to stream video to my xbox 360. Price is a bit steep, but the advantages are worth it.

Cons: Price.

Other Thoughts: Based on comments I've seen for Netgears powerline products, I wonder what the longevity of these are.

Pros: What can you say except that it works as expected

Cons: would like an easy way to wall mount either adaptor.

Other Thoughts: I have a multi level 4 pod home with metal roofs on each pod. All bad for wireless. This unit gave me an ethernet port in any room where I situated it. I combined this with an Asus pocket wireless access point (wl330g) and now can connect wireless at great speeds in any room/pad in my home.

Pros: Works perfectly right out of the box! Great for bridging a small wired lan to a wired- or wireless lan that's too far away for regular patch cable.

Cons: A bit pricey if you are going to plug in only one computer to a single terminal. If you want extra terminals it may cost $125 each.

Other Thoughts: I've always had a problem with getting a strong wireless signal into my room at home because the wireless router is on the other side of the house and I got sick of losing my signal every now and then so I bought these bad boys to see if they were a viable solution to my signal loss problem. I plugged the master adapter next to the router and the terminal router to my computer and, lo and behold, it works like a charm!

To me, the price is too steep to just plug one measley computer to the router. So to make it worth the 2 Benjamins I spent on it, I decided to plug my computer into a switch along with 2 other computers I had and then plugged the switch into the Panasonic and they all now have access to the internet.

These adapters are no speed demons since they max out at 42 Mbps but that is way more than enough for broadband internet. And since I wanted to hookup my computers to the internet, these work like a charm!

Pros: Best powerline product on the market.
I get 25-30 mbps throughout my house(I was getting 8mbps with netgear 102 homeplug turbo)

Cons: conflicts with homeplug turbo had to remove netgear 102

Other Thoughts: waiting for hd-plc 2

Pros: Consistency! I've used a wireless connection now for about 2 years only to get angrier when I'd lag out during online gaming. It wasnt bad, but just enough for me to crash my apache during Desert Combat ;) Now that i'm hardwired with the HD-PLC system, lagging out is a thing of the past.

Cons: Its not for those who seek mobility.

Other Thoughts: The advantage of this technology is that electric socket is everywhere inside a house. Right now, a broadband outlet still isn't usually available in every room, even in homes that have broadband connections. In the future home envisioned by Panasonic, people will be able to download and watch high-definition movies in any room of the house that has an outlet.
