As far as I can tell, a very good device. I have an old Win7 computer that was connected to my Comcast router with an Ethernet cable. I had to move this computer to another room and didn't want to install a long ethernet cable when I can connect via WiFi. The unit came quickly from Revain and was well packaged. The instructions are very clear and easy to follow. The on-screen prompts were exactly as described in the instructions. The device worked fine the first time it was plugged in and continues to work even if the PC goes to sleep while the device is still plugged into the USB port. It works even after shutting down and restarting the system without reconnecting. Performance is slightly better than Ethernet; Not being a computer genius, I don't know if this is expected or just a pleasant surprise. I definitely recommend this device; I think it's worth the higher price tag than the cheap ones I've seen in Revain reviews.
