This Polly Plastics rock tumbler grit and polish kit is top-notch — it gave our rocks a beautiful, smooth finish and everything in the kit worked exactly as advertised. The ceramic filler really helps with cushioning during the process, and the silicon carbide grit does the job right. But here’s the thing...Don’t use your tumbler in a Michigan garage at -10°F. Ours turned into a rock-shaped popsicle and completely seized up. Lesson learned: rock tumbling is not a winter sport unless you're doing it indoors with hot cocoa and a backup generator.To make things even funnier, when our parents came over, they heard the low rumbling from the garage and asked, “Why is your car running?” We had to explain, “It’s our rock tumbler.” They nodded slowly and still have no idea what that means. I'm pretty sure they think we’re up to something shady.That said, the grit and polish are excellent. Just keep it warm, keep your tumbler happy, and maybe warn visitors ahead of time that you’re not secretly building a spaceship in the garage.

Bought this more then once works great

I’ll use nothing but polyplastics for my tumbles!

Good price and quality!
