For some reason, my drummer misses practice a lot. To keep the rest of us tight, I thought it might be fun if we had a drum machine to play along to. We rent an hourly rehearsal space, so we don't have access to computers and stuff. (we're kind of old school) The UNO is portable, light weight, and easy to use. It hooks up easy and sounds great. My only drawback is that the instructions that come with it only describe the buttons on the device. To really learn what you can do with it, you have to go on-line. But who wouldn't do that anyway? I've had fun with it a few times now, without really knowing what I'm doing. This was exactly what I wanted!
