Summary: These work well in some rooms and not so well in others. I live in a 1100 sq ft apartment and cannot run cables and some of my TV's are not wireless. I tested this in two different rooms and one worked way better than the other. My internet speed is Comcast Blast 105Mbps and in one of our bedrooms across the apartment it works flawlessly and pulls anywhere from 80-90 Mbps which is great for that TV and Netflix etc.
Pros: Definitely a speed upgrade for me. I was using a usb wifi wireless adapter and thought I would try this. At first I had the noise coming through the speakers, and after some research, realized it's caused by having the powerline adapter plugged into a power strip. I plugged it directly into the wall and the problem was solved.
Good performance but cost you two grounding type power outlets

Summary: A good product to stream videos over the ac power-line. It saves you one AC plug, but cost you two grounding type power outlets. The reason for this is that the device's case is too big and will cover the grounding part of a standard NEMA 2 plug receptacle. But, it's still possible to plug-in an ac cord without grounding wire. Wished they would have taken their measurements right before putting this on the market.
Summary: Fantastic purchase. Very easy set-up. My wifi speeds went from 6 Mbps--> 35-40 Mbps. I bought these to extend my Airport extreme wifi network. One unit plugged into AEX (which is connected to fios modem/router with wifi turned off) via ethernet. Other unit across the house plugged into ethernet port of Airport express. I set of the express as a new wireless network with the same SSID/security/password via airport utility. Turned on encryption on the zyxel units.
Summary: I use this product to connect my Blu-Ray set-top box to my home router. The acid test for me was being able to stream HD content from VUDU, Netflix, and Hulu without a single hiccup. Product was ridiculously easy to setup, and did not block access to my second outlet like some have reported. One minor annoyance is that I sometimes have to restart the streaming application if the unit has gone into power saving mode in order to establish a connection.
A great way to get a hardwired connection without needing to run Ethernet

Summary: These HomePlug power line adapters worked better than I expected. I have yet to run Ethernet through th house and this will help me push that off until I need to do that. I have a 100+ year old house but the wiring is all new. Wifi signals have been spotty from the back of the house. With this power line adapter kit I was able to add a wireless extension that's on Ethernet and it's solid.
Warning: Don't use more than 2 of these devices at a time!

Summary: Update 3/6/15 If you do buy these devices, I'd recommend purchasing power noise filtering devices for any sensitive electronics you may have, eg. computers, routers, TVs, stereo equipment, etc. I purchased Tripp Lite Isobars. Don't plug these devices into the isobars though. They communicate via the noise they generate on the power wiring and that noise is filtered out. Update 2/27/2015 Down rating from 5 stars to 2 stars.
