Pros: Setup was, literally, the click of a two buttons to join my existing powerline network. Don't tell, but I even set mine up through a power strip and haven't had any issues.

Cons: Nothing to complain about.

Other Thoughts: I think wireless is the only thing that can really complicate these powerline networks, and I just set up my second variant of that and it was easy, too.

Pros: -Easy to setup
-I get the speed that I pay for
-Convenient (I know hard wire is the best connection, but I don't have that option and wifi kinda sucks in my room signal is poor)

Cons: -No pass thru (but hey I bought the cheaper one)
-False advertisement (500mb is a fluke)

Other Thoughts: -I would highly recommend this product to those people that doesn't have the option of running a cable from a router to the device/machine or of the computer's spot has weak wifi connection

-I was in doubt at first when I bought it, almost returned it to Newegg so I can just buy a wifi adapter, but signal in my room is really weak so I decided to give it a try and hey I works perfectly for me!

Pros: Good power line and easy to setup and
Good range.
Good speed's keeps up with my 200/20.

Cons: None.

Pros: I rent an old townhouse with roommates. This goes from the ground floor at 85Mbps with 2ms ping to the third floor at 25Mbps with 12ms ping. For all the interference and distance in the building it is pretty good.

Cons: Sometimes need to unplug and plug back in to work, just like a router.

Other Thoughts: Would recommend
There may be faster ones now though

Pros: Yeah, I'm going with the consensus here in that this a pretty good product. My kids run wifi upstairs in our split level home while the fairly junky Frontier/Actiontech router (Rev. I) sits downstairs. They were having random disconnects and I tried quite a few things before deciding on this as another thing to try. Amazingly easy set up and 2 cables were included.

As others have said, plug it directly into an outlet on both sides. I didn't even bother trying a power strip or surge protector based on what I read. I also initially plugged the receiving unit in the "next plug over" in the bottom floor to initially establish a connection.

Took it upstairs, did a sync again and bam, connected.

I did not try any local network file transfers as that is not something we typically do. My purpose for this product was to get the kids a stable, decent connection. It did that.

Cons: None that I can really think of. The lights are not that bright. They blink in a logical manner when they are connected. I guess I wish there was an easier way to determine if the link is encrypted. I followed the instructions so I'm assuming it is...

Other Thoughts: One interesting thing is we plugged this in to several outlets in my son's room and did speed tests after every one (I'm talking internet speed tests, not file transfers). There was a discrepancy between outlets that was not entirely expected. Oh, we run FIOS 30/30.

So, on one outlet we would get 16/16. Another, 7/13 (pretty weird, that one). We settled on a plug close by that's next to a dresser and out of the way and got 13/13. We're happy with that. Also, all ping tests to the outside improved dramatically over the previous wifi connection and, again, were much more stable.

He is quite happy with this, as am I. My next step is to consider buying another set for my daughter's room.

Pros: It is plug and play. Really!
The secure connection option was painless too: Click the button on both units...and play.
I have a fine wifi setup: 30mbps write & 25mbps read
TP-Link boost it up to 49mbpr write 49mbps read.
Good enough, considering

Cons: None, except: It could be faster, as always.

Other Thoughts: My house is a recent, so the electrical wiring system is too and built according to norms.
This review is based on just a few hours after install. Crossing my fingers for long term reliability.

Pros: is a great addition to any online home. Just plug one box into the wall near the modem and run your ethernet cable to the box. Now you have a spare ethernet port anywhere in your home where there is a wall outlet. very simple procedure with no software to be installed and no more searching for "hotspots" in your home where your wireless adapter gets a good clear signal, just plug in to hard-wired ethernet anywhere.
also a great addition is when not in use the powerline nano adapter has a power save mode.
offers ~100Mbps no matter where it is in our home.

Cons: i couldn't find any flaw with the design or the functionality. the only con i could see is it advertising 500Mbps but only ever hitting ~100Mbps.

Other Thoughts: could only add up to four of these in our home, it would be great if I could just leave one plugged in every room of the house.
any newly manufactured home should offer this type of connection to fit every room. just an ethernet port on every electrical outlet.

Pros: Considerably faster than N rated Wifi ....

Cons: Although it gets "up to 500Mbps" ... really just expect a 100Mbps connection... .

Other Thoughts: for 35 bux... its not to bad of a product..

Pros: I've had a three of these things in my home for about a year. During that time they've mostly worked great. Primary use has been for streaming video and audio from a server located in my home office and from the internet via a router located in my home office. Connections go through breakers in my power system and generally work well. In the first year of use I would occasionally (maybe once a month) need to reset one or the other of the powerline adapters. This was irritating, but not a deal breaker.

Cons: Recently, the living room powerline adapter started needing to be reset more frequently; often multiple times a day. This would usually happen while streaming video from my server and, less often, while streaming from the internet (Netflix, Hulu, etc). I swapped the adapter near the living room TV for a different one (I bought two kits but was only using three of the adapters) and saw no improvement. I suspect that the problem is not with the powerline adapters, but that something has changed in the local power grid that's giving the adapters problems. The adapter that needed frequent resetting is on a different breaker from the adapter the server and router are on. A third adapter in my bedroom is on the same breaker as the home office adapter and continues to work fine for streaming.

Other Thoughts: I got a Steam Link (a device that lets me play PC games on my TV as if I were sitting at the PC) for Christmas. The Steam Link and my gaming PC were connected via powerline. This would work for a few seconds and then hang. I turned on diagnostics and noticed that lag over the powerline connection was normally about 60 ms but would spike to several hundred ms every few seconds. Steam Link is very sensitive to lag and this problem made the powerline adapter unusable for that purpose. I suspect that these spikes are also responsible for the need to frequently reset the living room adapter. To resolve the problem I ended up running CAT5e cable under my house and eliminating the powerline connection between my home office and my living room. The powerline connection between my home office and my bedroom continues to work well.

TL;DR When these work, they work very well. They may or may not work in your particular house's power grid. They work better when they're both on the same breaker. They are probably not a good solution for any application that requires minimal lag time between devices.

Pros: Setup only took about 2 minutes out of the box. Using this over a wifi adapter has gotten me from >1 mbps speeds to about 15 mbps which is as fast as my internet connection gets. This was well worth the price

Cons: None.

Other Thoughts: I would recommend this product to anyone who wants to have a faster connection away from their main router without worrying about getting another modem+router and all that. This product has a much easier setup and a lower price.
