using this with a gewa g9 so keep that in mind when reviewing. this is thin and very similar to atv/efnote in terms of playability and feel. there are differences, but it is nice to play on and works well. not as trigger responsive as a roland. but with the right settings it works well. but nice to play on. even though it triggers 360 it comes with a rotation stopper. it is good, but the construction makes me ambivalent. the bottom is great, but the little plastic piece on the top could have been a little more adapted to the size of the hole.
