I live in an older house that is almost impossible to run cables without having them be extremely visible. I rely heavily on wireless, but with my modem and router in the office upstairs, all my devices in my living room and bedroom(downstairs) only ran on a 75% or less signal. I've tried boosters and repositioning my router, but with little improvement.
I've had this kit for seven months and I haven't had to do anything since installation, which was a breeze. I simply plugged one of the units into the nearest power outlet by my router and connected it using the provided Ethernet cable. I attached the other end to the AC unit behind my cabinet containing my desktop hooked up to my 47" LCD. Now, the desktop gets wired and wireless signals. I used to have issues with online video buffering, but have not experienced that since installation.
This works so well, that I recently bought another to connect to my Xbox and Series3 TiVo in the bedroom.
I'm unsure about the power usage, but I highly recommend this for anyone who wants to easily network older technology that heavily relies on data transfer.
I bought these because I needed to be able to hook my DVRs to my network. It would have been difficult for me to run a hardwired Ethernet setup across the house. So I bought these to try and avoid having to hardwire across the house and they are working fine. I simply took them out of the box and they immediately saw each other in different rooms of the house and are communicating at greater than 80 MBPS.
This product appears to be everything I hoped it would be and simple to install understates the amount of effort required to hook them up.
BTW, one hint that worked for me immediately. These units come with a default encryption password. The units can also easily change their encryption password by simply pushing a button on each unit. HOWEVER, it is important to push the buttons for only two seconds. Not more, not less. Knowing that I was able to change the default password successfully the first time.
