Does what it says on the tin
Worked fine with little setup and few issues. Most importantly for me, it works on Windows 7 64-bit.

Works flawlessly
I got it so I could use the React PS2 Wireless Controller on my PC. I had to configure it some so the buttons would be setup the way I like them. There is no lag regarding communication between the PC, it and the controller that's plugged into it. If you're looking for a great way to play games on your PC wirelessly, I suggest doing what I did.

Great adapter
The drivers could use a slight touch up, but overall the quality of these adapters are great. I bought 2 so I could use both my DDR Dance Pads for Stepmania, and they work beautifully.

Excellent!
This item is excellent! It is a fair price and works magnificent! No problems whatsoever and its simple plug and play, and if it happens not to work as soon as plugged in there is a handy manual included to help set things up! I will definitely be buying from here again! 5/5 Satisfied and Happy Customer!

Works out of the box
Awesome product, got 2 of them like 9 months ago and till today it is still functioning well.

It even works straight out of the box on my Mac OSX Leopard without any drivers.

Awesome product, Awesome price, Awesome Seller.
