Review on Home Pro Shop Cup Turner Kit: Ultimate Tumbler Spinner for Crafters - DIY Glitter Epoxy Made Easy! Cup Tumbler Turner Machine Kit + Bonus Starter Kit by Carol Miller

Easy to use. It has a switch to turn on and off. The instructions are easy to follow. It was easy to assemble. The foam is a long sticky-backed strip that you tape to a plastic tube and roll up. Sticks to itself. I thought it came with a hard piece of foam (something like pool noodles) but it doesn't. This foam strip allows you to adapt to smaller cups. Just don't wrap all the foam around the pipe. I'm not sure how long this will last, but you can always swap it out with a different type of foam later. So far this has worked great! Will most likely buy another one once I test this one a little longer.
