Millenium MPS-750X Expansion Pack

It is a very good product. I think that you should buy it for better drumset. Easy setup.

I really bought this for the extra Cymbal, which I'm very happy with. I'm not so sold on the Drum pad. Mostly because, on my kit at least, if I hit it simultaneously with another drum pad, the other doesn't sound unless I hit right over the sensor. It's also set much, much louder than the other pads by default. I suppose it might come in handy for 'in the air tonight'. :)
PS I found it quite difficult to fit the drum pad along side the existing pad on the kit. It's on but it's a tight squeeze.

I wish it was two-zoned and a little better response time.
