I bought this to replace the Nintendo Motion Plus Adapter which is getting old and unresponsive after a short use but this one is worse. This controller is very sluggish; During sword fights in sports facilities, my sword collapses and usually ends up facing backwards within a 60 second fight. A few seconds of inactivity and he'll face forward again. Tried for an hour on two original controllers and one third party controller - no difference. For comparison, I still have the original adapter working. Might be good for games that don't require quick action so I gave it 2 stars but can't use it for games that require quick responses lasting more than a few seconds.
