It works really good it's plug-and play no drivers needed, 99.9% of the converters doesn't need drivers, i haven't check the lag I have pretty much have every commercial converter for different controllers, but i have to make my own for a few "To accurately test your adapter/converter, you need to: 1) Using a key on your keyboard to run through the program once and record down the input lag time from your keyboard. 2) Plug your gamepad and stick through the adapter that you want to test into your PC. Then, use programs like (xpadder) to map a button on your gamepad or stick to the SAME key that you tested in step one. Run the program and record down the input lag again. 3) Subtract the two results you got from previous steps. If the difference is less than 2 ms (i.e., stick input lag - keyboard input lag <= 2ms), then your adapter can be considered as lag free." really only important if you play street fighter type of games
