I use this pad to load my own samples, and have gigged with it a few times since purchasing.
It's very well built, and can take quite a bit of punishment. Is also very easy to use, both when programming it and when playing live.
Very simple to load and customise the playback of each sample - just USB connection to computer, then drag and drop WAVs into it.
I had it mounted from a crash cymbal stand live, and was worried about inadvertently triggering it with vibrations through the hardware. The threshold adjustment is very easy to use, even on a dark stage, and I found that even without being able to hear the pad I could adjust the threshold effectively with the aid of the "trigger" light on the front of the pad.
I would recommend this highly to anybody looking to add electronics to their set up who doesn't want to splash out just yet on some of the bigger pads (SPD20 etc), or anyone who wants to be able to trigger sounds / backing tracks / click tracks easily live. Very easy to play with sticks, hands or feet.
Well worth the money
