Query: Excellent practice tool.

Great item. I am impressed with mine. I don't know what the other reviewer is talking about because I love playing on this thing. It's a 8 and a half inch diameter and 1/4 inch thick tough rubber mat that just rolls out on any hard flat surface. It displays the notation for all the rudiments which is helpful. You can basically stuff it or crunch it up and stick it your pocket or book bag and go anywhere with it, always having a practice pad with you. Most of the name brand practice pads I have played on either were too loud (which defeats the purpose of the practice pad) or felt like I was hitting a block of wood, this Rudi-Pad feels right, very close in feel to an actual drum skin. It's better then standard hardwood/gum rubber+neoprene practice pads out there today (Vic Firth, HQ, Aqaurian,) because it hardly makes any noise, doesn't weigh anything and doesn't take up space. Being able to take this anywhere virtually doubles you practice time too.Recommended.
