Pros: Pass through feature so we do not lose an outlet.
Solid speed.
Easy to setup.
Provides wired internet to a location in home with no web or only wireless.

Cons: None

Other Thoughts: I used this in my daughters bedroom. She has always used wireless to her PC which works fine most of the time but drops on occasion which can be a real pain. I attached this unit to her wall outlet (I was able to plug her lamp into the AV2 MIMO which is a nice feature), attached the other unit at the outlet near my wireless router, plugged in the cables which were included to both the router and the PC then BAM! wired internet!! Speed is solid and very comparable to the wireless that she was using. We have been testing this for a month now and we have not had a single issue. Works as advertised. This totally beats me crawling under my home to run a longer cat5 cable to her room and it beats the wireless internet that she was using. She's happy and getting less lag when online and that in turn makes me happy.

Pros: No messy wires running across the home, good performance, easy to use, surprisingly good range

Cons: None!

Other Thoughts: This device is great! I currently have LAN wires running across the home and I've been meaning to find a good solution to this. We have so many devices, it cripples even the best wireless routers we can find. Our cable modem and router are located on the 2nd floor but my computer is located in the basement. I was surprised that the two devices could talk to each other- despite being that far apart.

Performance is a little lower than expected. I am seeingabout 70-80Mbps while my wireless can reach 110Mbps easily. But there isn't a picture perfect solution to everything. It's not wireless which can drop off randomly and it increases safety by eliminating open wires. I do notice on occasion the random lag spike- probably due to the circuit line quality. But it doesn't happen often and the performance is solid. I have yet to add more PoE adapters but definitely plan on doing so.

If you've been looking at using PoE in your home I highly recommend this product!

Pros: Hasn't dropped out once in the 4 months that I've owned it
Easy installation
Fast as my fully wired connection to another computer

Cons: Bulky
Can barely use the other plug on the outlet plate because this is so large, definitely need the pass through
One outlet didn't work so I moved it over on the wall to another and works fine

Pros: - Fast connection speeds
- Pass-through power outlets (no more eating up an outlet)
- Easy set up
- 2 year warranty
- 128-bit AES Encryption
- RJ45 network cables included
- Great if you want a "wired" connection without running cables across the house

Cons: None.

Other Thoughts: I have reviewed plenty of powerline adapters and these are the fastest ones yet in regards to network connectivity. My complaint with power line adapters was that they "took" a power outlet since they cannot be connected to a surge protector and have to be connected directly to the wall. The added pass-through power outlets are a nice touch and polishes off the incomplete design of the older powerline adapters making this a completed design. The speeds are fast and will require a router that is capable of handling speeds of 1200Mbits per second.

Set up was a breeze and just requires pressing a button on the units. These are truly plug and play and were up and running in a matter of a few minutes. These also play nicely with other powerline kits. I tested them with a Netgear kit and another set of TP-Link adapters and they worked great.

If you want to have a wired connection but can't run network cable neatly then powerline adapters are great and this one is one of the best. With the added pass-through power outlet, you won't have to worry about "wasting" a plug again.

Pros: -2 year Warranty
-24/7 Tech support
-Plug and Play
-984 ft. range over electrical circuit
-128 bit powerline security
-Manual very clear and easy to follow.

To achieve 1,200Mbps you'd need devices that can achieve no less than 1,200Mbps, in other words AC networking.

Set up was extremely easy, took no more than 3 minutes in the actual process, from thereon it did not require drivers installation or any other kind of software or firmware or app, just plug and play.

In my first run I used it wired from an outlet which unfortunately had an integrated 6 outlet surge protector (according to the manual a surge protector is not recommended for this to be plugged in), not a strip but nevertheless I tried. First with the wireless connection I was getting 26/30Mbps, now wired and the surge I was getting 40/50Mbps. Not bad.
There were no glitches, no dropped signals even during busy weekend hours of the day and night.

Streaming was good, from all well known sites and cable services.

2nd step was to bring my wireless Linksys AC 1200 router to my room (I have the range extender in my bedroom but even with it I was getting 26/30Mbps, very slow considering my speeds are 75/75Mbps), so I unplugged the AC router from the main cable/router downstairs and this time I put the POWERLINE adapter in an outlet which there was no "surge protector", plug the Linksys AC router into the powerline adapter and tested the wireless speed and I am gettin 50/60Mbps (35/41Mbps lowest) average, with 61/73Mbps the highest I've seen. Dramatic improvement, now I feel like I'm getting my money's worth from the AC router and cable/internet fees.

3rd step, checking with XBOX, when my AC router was downstairs I'd get drops all the time and it became annoying so I used the main cable/router to connect but still had low signal but no drops.
With the AC in my bedroom now, XBOX live has no glitches, full wireless bars, streaming is flawless, not a single drop in signal for 5 days straight and counting.

Overall, it's a fantastic unit and way much better than to run ethernet cables through out the house, the speeds improved dramatically, never thought I could achieve them with all the wall in my house and in all 3 levels.
This unit is worth every penny and it's a great tool to expand your network around your house w/o slowing down your internet speeds.

Best part in my opinion, if your cable company provides a router, now you can have a wireless AC router in the 2nd level w/o having to buy a range extender, if you want to keep your home wires free. Now all of my 3 bedrooms upstairs I get full bars for wireless signal in all devices we use in the home.

Cons: None.

Other Thoughts: Internet in every room and every floor w/o running cables in the entire home, using existing powerlines.

***EDIT:
Been using this since October on a daily basis for more than two hours a day and I'm yet to have any issues with it, it certainly is much better than to have wires all over the house or trying to hide them, with these units I can make any outlet an internet connection outlet in the house. One of the best items I've reviewed so far, it's convenient and never have to worry about 50ft cat5 cables, kinda like wireless.

But yeah, no issues of any kind, always connected and downloads as fast as the speed is rated from my service provider.

Pros: I really like these powerline ethernet adapters. You can literally just plug them into the wall and your ready to go. I know a lot of people have complained about the speed, and I agree, its no where close to 1200mbps. However, I am currently getting about 366mbps (45MBs), which is really good, and faster than wifi. I think most of the problems folks are running into with slow speeds is caused by the wiring in their homes. My house was built in 1994, so its fairly new electrical and I've seen a very stable connection over about a 100ft run.

Cons: The advertised speed is pretty inaccurate, though these still are capable of performing much faster than wifi.

Other Thoughts: I'd recommend you give these adapters a try if you have a newer home with modern wiring. Its so much easier to just plug these into the outlets than run cat6 throughout your home.

Pros: One of the pair work great! Was able to add a wireless extension into the network and it works flawlessly.

Cons: The second passthrough module has to be consistently reconnected. It seems like some "green" power saving tech kicks in, and then loses the connection. They are junk is too harsh (but all I can think of at the moment), and I would have returned the entire kit had the wireless module not connected right away, with no other problems.

Pros: 20 MB/s (160 mbps) performance . Has a much needed power pass-through because it is bulky.

Cons: Connection drops out over the same 50 feet circuit a few times a month, and TV recordings being carried over the connection have holes in them. The adapter is also rather bulky.

Pros: Worked great right out of the box.. it even works plugged into an el cheapo powerstrip surge protector (which was necessary due to the size of this and a lack of space at the one outlet i needed to use)

Cons: Size. It kinda eats up an entire outlet. To work around this I plugged it into a cheap surge protector. This might not work for everyone.

Other Thoughts: Fantastic. Idiot proof.

Pros: - Significant improvements in speed.

- Significant improvements in consistency of operation.

- Significant improvements in firmware.

- Speeds achieved are a far cry from "1200" Mbps, but the speeds are consistent and may be superior to WiFi. The plethora of WiFi that now exists and folks thinking/keeping the transmit power to max (when low or medium would achieve maximum possible speed) - often makes WiFi less than optimal.

- Best performance when both units are on the same phase circuit.

Cons: - Still not 1Gbps wire speed.

- House 'wiring' still a significant limiting factor. (see other)

- 'Power hungry' appliances (noisy ones) can have a significant impact.

-A 'very noisy' light bulb on the circuit can present a ~30% drop in speed.

- Excessively large to the point that it's "one item" per duplex outlet for electrical use.

- Lack of activity indicators.

- Instructions need to be reviewed for accuracy.

- Speed should be advertised using realistic value. Max upload + max download speed isn't helping the consumer.

Other Thoughts: - Electrical wiring codes, while intended to be 'beneficial' never took into consideration that the wiring might also be used for data transmission. Thus, the wiring itself can be a hurdle.

- When tested on a dedicated run that was breaker panel to an outlet to another outlet, roughly 75+ feet in-between outlets and nothing attached but the units - achieved excellent (and consistent) speeds. Between breaker and first outlet a power line conditioner exists that also filters out 'noise' and nothing else on the circuit (unusual for most cases). It's a scenario that most people likely wouldn't have.

- Even certain types of lighting can present hurdles. Example, an inexpensive bulb created a lot of noise (reduced speed) vs. a more expensive 'better' bulb (generated less noise) had less impact impact (faster speed).

- If you're looking at using this for wired networking it's definitely an option. The technology has gotten far better (than it used to be), still not perfect.

- While many factors can impact it, one can't expect excellent results if there's a lot of noisy appliances/lights on that same circuit. Depending on where you live and how densely populated - may increase the ambient noise coming into your house.

- To get the most from this type of technology, it requires some consideration and some testing, likely some spend (better quality items on that circuit) and perhaps a bit of luck to find the right circuit(s), unless you know which circuit(s) are your best route.

- Would certainly recommend, but that comes with some effort - it's not "plug and go".
