Spotty at best, shuts down when too warm (happened a few times sitting next to the 470 while gaming) but it's cheap.

I wasn't expecting much from it so...it's fine.

Very easy to install using a PCI express port. This has a good speed for most consumer wireless connection needs. The low profile faceplace didn't match my case's black look so that was a drawback.

Not the best. Install was easy, and ping is alright, but download speeds are SLOOOOOOW. Like 5 MB/S slow. The router is only 4 rooms away.

Great wireless card, very easy to install. I did take one star off not because of the speed, but because the range was a bit on the bad side but other than that it's a great card and is pretty fast.
