I have an older Grobet 47.782 tumbler (circa ~ 2010) and the drive belt broke. I searched everywhere and by chance found this replacement.. Works perfectly and I'm up and running again. Package arrived quickly and I am a very happy customer.

We have a Thumler's Tumber Model B purchased in 1999 that was used once and then stashed away. Over time the old belt solidified and then fragmented. Because the motor still runs this seemed like a good investment to see if the thing would still polish stone. The replacement belt fit nice and snug, and the tumbler's been tumbling a load of agates now for a week without any issues. Given that it looks and feels like it's made from good quality material I expect the belt will last longer than the poor old motor! Fine product for a lower price than I expected to find!

The fit was perfect however, the first band broke only after 5 days if use. So far the second band has held up it is on day 4 so I am hopeful. I still feel it is a good product and would repurchase.

Excellent quality replacement drive belt for our Rock Tumbler. Good quality and easy to snap on, it's worked very well since installation. Looks & feels (and as above performs) just like the OEM belt. Buy with confidence that it's not just some cheap knockoff replacement part.

Do not buy these belts. I have a 3 pound rock tumbler and have broken 2 belts in two weeks. My tumbler is in good working order, the pulleys have been checked for alignment, and I have not overloaded the tumbler. I'm on my third belt, but expect it will fail soon. I suspect these are really o-rings and not actual belts. Belts are designed to be under some tension whereas o-rings are not and fail when put under tension for any length of time. More annoyed than anything else because now I have to order more belts to get though this run of rocks. Grrr!

They fit my Thumler Model B Tumbler perfectly but soon started slipping and did not last long at all. Belts from a different source, although a bit higher in price, are much better (still on the first one of those vs. three of these).
