Pros: I have an old house with plaster/lathe walls. My router is a D-Link DIR-635 (sunk my $$ in the heart of the system) which is three thick walls and a staircase away. The signal strength on the computer hooked to this USB adapter is consistent at 70% with MAX data pass through rate. I have not had the issues with lost connectivity/dropped packets others have mentioned.

Cons: Instructions are lacking for a newbie like me, but I was able to get it going after just a couple of minutes fussing with the included software.

Overall Review: Can't touch it for the money. Especially if you are limping along an old windows 98 computer like my decrepit but faithful eMachine. Most of the new adapters aren't backwards compatible that far.
