Pros: The product works as advertised. If installed as mentioned you get really good speeds.

Cons: - These units get pretty warm when they are only plugged in for a few minutes.
- Caused all other units connected to it to heat up excessively and degraded how they functioned
-They are so large that they cover the other outlet in the plug to the point it could not be used by other three plug connections.

Other Thoughts: I had two of these units connected to a new Netgear wireless router and it heater the router up to the point that it was hot to the touch. Additionally this increased heat caused the WiFi to degrade to a point that units trying to connect to in the same room would not connect. Once I disconnected the ZyXEL units from the router and it cooled down (no heat to the touch) WiFi functioned as expected.

This seemed like a really good option, but after seeing the results, I'm going to run good old dependable Ethernet cables.

Pros: I purchased two sets after getting inconsistent speeds with the TP-Link products I was using. My Internet cable speed (Comcast) is 88-89 Mbps and only one of the three TP-Link adapters tested that fast. The other two never speed-tested past 65 Mbps for some reason. I received and installed the adapters today and am happy to say that all three units speed tested at the 88-89 Mbps speed that I get on my desktop that is connected to my modem. I watched a TV show using the Crackle App and the picture quality was much better with the increased speed.

Cons: The unit has different light colors based on the speed. For some reason, one adapter occasionally turns orange (20-80 Mbps) but the speed tests at the maximum, 88-89 Mbps.

Other Thoughts: I am happy with this purchase. Worked as expected.

Side note. I do not use the CAT-5 cables that were included. I have CAT-7 cables and used them instead.
