When I was younger, I played "air drums" all the time. Even now when trying to figure out a part I will use the "air drum" kit.
This is want got my attention with this product. The "air drum" aspect.
I have a Trigger Finger that I use for midi input. It works great and I wouldn't want to do without it. However, there are times when I just can't get the feeling down like I want. But knowing if I had a drum set with triggers it wouldn't be a problem getting the feel right off the bat.
When I saw this product, the above was the first thing that went through my mind.
