Drum Kit Calculator

Add a new element to boring calculating! Each key has a different drum or cymbal sound. You can also turn off the sound if you want, but it isn't that loud.

great

idk just want this to have a review

Bought this for my son for Christmas, slightly over shadowed by the full size drum kit his uncle gave him! However for the hours between blowing every other gift out of his hemisphere, he really liked it!. It is a cool little gadget, my son loves numbers and beat boxing. Brilliant!

Nice novelty item, ok as a bit of a gag gift, but the build quality is cheap and flimsy and the drum sounds are very quiet... no off button either... poor.
