Summary: This is a great item. I acquired an older MAC without Airport and short of buying a Airport card and installing, I opted to try this. Easy to use, instructions might be a little more specific, but pretty easy to figure out. Only took about 10-15 minutes to connect my MAC to my wireless home network. As an addition, Walmart showed the delivery date on the shipping order and it arrived 2 days early. Walmarts' delivery has ALWAYS been before the date promised.
Summary: I got great reception and the price was fantastic. I used it with a PC and never had an issue. Better than the wifi card built in! Get one if you need a mini wifi adapter. It's small and great.
Summary: This is my second time buying one of those. The first one I got for my wife's netbook about 6 months ago to replace her dead internal adapter; she's still using it, with no complaints. Then came time for me to build an HTPC. I didn’t have room for an internal adapter, so I bought this instead. It's been working great! No interruptions while streaming, or downloading. It's fast, but there are faster options available.
Pros: Super Small, and fast!
Cons: But not the fastest USB adapter out there....
