First things first, the trigger works flawlessly and its easy to use, to connect it and to install it.
I bought it to be used with a Yamaha a DD-65. And also to use it with other MIDI Drums that may come to my studio at some point in the future.
It's made of nice metal and good rubber, though I think the rubber could have been a little less crumbly, its not that is cheap and will crumble easily though. it's just that if your pedal got a white maze like mine it will get black instantly in the part that touches the rubber, not that important really, just trying to be detailed here.
Also you must be aware that it doesn't have any foots, nor pads under it, its meant to be over a carpet and because of it if you use it directly over the floor it may be way to noisy and end up annoying some neighbors, I workaround-ed it by putting some really thick fabric to slightly damp it.
Also in the rear part of it, you'll find a knob meant to increase or decrease the sensibility, and I must say, that it works marvelously when you need to find the right spot so your kicks aren't always too loud or to quiet.
In the end, it works nice, and seems that it will endure a large amount of years of usage.
Don't hesitate, if you need a pedal trigger buy it now!
