Before I run out and get these for my Wii-motes, I was wondering what people have thought about the Motion Plus. Is it too responsive, not responsive enough or just right?

It can be unresponsive at times but it depends on the game. Other than that I have no real issues with it.

Which game are you having problems with? Will this help improve some of the response issues with games like Wii Sports? Thanks

Motion Plus is what the Wii should have been to begin with, I don't even know why Nintendo is charging so much for it and even bundled with Wii Fit Plus (as far as I know) to begin with. >_>

Short: Buy it, you'll be glad you did.
