Top critical review
I would look at other solutions before recommending you try these

UPDATE Jan 2016: Dropping to 1 star. I have had to reconfigure these multiple times as the 2 wireless slaves keep "losing their config" in some way. And getting everything synced back up is a multi step nightmare of a process. I removed these and went with a high power TPLink wifi router It doesn't give me the coverage these did, but at least it is reliable.
I bought these to try to solve weak wifi issues in my multi-story house. While they appear to be working and solving that issue, setup is a much more convoluted process than should be necessary. I ran into at least 2 undocumented issues with the '1 wired, 2 wireless' setup I needed. I found solutions via a Google search, but only after i had wasted a few hours following the product administrators guide over and over trying to make it work. Also, the management solution is a 'console' that you have to run on a PC on the network. It really needs to run constantly, but i don't have a PC that is on 24x7. It works, but if you are accustomed to managing devices by hitting their builtin web gui directly, you will find this to be a cumbersome process.
