I was fully prepared to buy an entire stand, controller and pad but all i needed was the controller so this being available looked like a great option.
My 2 main concerns were whether it would be compatible with my Alesis module, and then whether I'd be able to figure out how to actually hook it up (this is my first "proper" moving HH system).
But it's all been great - the actual controller is just a pressure switch on the top so it was pretty clear how to get it working once i actually had it in my hands. And it functions with no real issues with my DM10 module - although it's only open or closed but that suits me for now.
Overall a great low cost option for something that seems to be compatible with lots of modules.
