This little thing is absolutely fantastic. So fast and easy to use, and the compact size makes it very easy to manipulate in the space between the dubbing loop and table/vice base. The design is perfect with the roto head, and the loop for your finger...get that dubbing loop set, give a couple gentle turns to get started then a hard push with the thumb and it spins on its bearings like it's got a motor. Honestly not sure how it could possibly be improved!
