Where to start ... this article is simply essential for a good grip. With large (and large) hands I felt great discomfort see pain in the thumbs and palms after 30 minutes of play. After 2 hours of use on smash bros in the company of this "add on" to the 3ds I can not separate myself! Children may be embarrassed by an R button a little way because of the "extension 3cm" on the right side but adults will find their account. Only downside, the number of games is compatible with the right stick is really very limited. But laccessoire remains usable as is (without ZR and R button right stick) and which I think is a real plus for playing comfort.
