This is the first time I m using this kind of hihat for e-drum and I have to say I was a little disappointed. I was expecting something more realistic, close to a natural feeling, but the real problem is that its really hard to keep the hihat closed. It needs hard pressure. Also, you have to choose wisely the hihat stand, make sure that it has a rotation control. Of course the sound quality is very good if you combine it with a Yamaha module and its a lot better than using the pad and the hihat control pedal.
