Rock Tumbler PU Replacement Belt for K1 & K1 Pro – Upgraded Durable Anti-Break Design, Not Compatible with Other Models – 5 Pack

Works well if you follow the steps...

I really didn’t know what to expect when I ordered these. The ones that came with the rock tumbler didn’t last 24 hours each. These are lasting 2 weeks. I will continue to use these for my tumbler

The media could not be loaded. I have a no-name rock tumbler with no company website. Not a junker, but not high dollar either. Its belts, when broken, are 8 7/8” long. So if your current belts are between 8 3/4” and 9” (possibly even 8 1/2”) these will work fine. No slip, good grip, and the one I’ve put on it has lasted 9 days so far (a record).

Works great for my rock tumbler. Only used it twice to tumble rocks so not sure the longevity of it yet.

These belts are perfect size replacements on my tumbler! I never wanted to be particularly done with a tumbling session and have to wait for a replacement,these are perfect.By the way the original belt is going to last a long while,very good quality.

Rubber belts for your tumbler break - no matter what you do. These replacement belts have worked very well for me. Some have lasted for close to a month with my Komestone tumbler before breaking. You can't tumble without belts - I always make sure that I have some on hand. I'd definitely recommend these and will be sure to purchase more in the future.

The belts appear heavy duty.However, they only last on my rock tumbler for about two weeks, than I'm replacing them again.

Received the 5-pack of belts but 2 of them were different size and are not usable on my tumbler. The other 3 are just fine and got me up and running again. 3 of 5 stars for 3 of 5 belts.Edit - the belts only last about 5 days before breaking. Out of the three belts that fit, two have broken and I'm now on the last one. Almost made it to stage 2.
