No complaints. Very good product.

I live in a house or wifi is non-existent because the marrow filtered by large granite bearing wall. One solution, the CPL (ethernet cables draw for me was impossible).
This product perfectly filled his office. Easy Association via the small button on the side of the case. Direct recognition by the second module. Well enough flow to the Internet (surf / mail, etc.). I have over 80Mbits / sec throughput. And in between there are 4 levels (ground floor, 1st, 2nd, and 3rd floor). It is Plug & Play to install anything to solve or anything else. You plug it into an outlet (preferably non strips) is associated, and connects their device. 1 min I got my PS3 internet to play online.
Plus they are compatible with other models in the range. I have six in total, 2 of the 2101 series and 4 of the 2001 Series wifi, and all these people works in perfect symbiosis with the Livebox.
So no complaints by advise you to take it.
PS: I limited myself to a 200Mbit / s because beyond it has no interest if it is just to go on the internet which in most cases is capped at 15 / 20Mbits / s. Beyond this is more marketing than anything else. Except if you want to use it to transfer files on your local network (server, NAS, home network between computers).
