I can't say anything for their reliability, never really heard of them. It's pretty much impossible to get into the proven brands on a $20 price budget. You'd need to get up a little further, probably in the $40-60 range. If you are interested, I'd recommend the Asus and Linksys USB sticks. Also, using a USB 2.0 device in a 3.0 port works just fine. USB 3.0 ports are backwards compatible with 2.0 devices.
