I've had my tumbler for over 35 years. It's finally due some new parts. Very satisfied with this tumbler and glad replacement parts are still available. When you have got a good quality product, no need to mess with it.

Company Response

Hello Kevin,  We really enjoy hearing from people who have a Thumler's Tumbler that they have been running for 35 years.  I know that you have taken good care of it.   Mr. Thumler (that's really his name) is still making the tumblers and making replacement parts to keep all of his machines running.  We have one running here that my father gave me as a Christmas gift in the 1960s.  Hobart King, owner / manager, RockTumbler.com

Good reviews on tuml'er products, had R2 up & running in a day's time. Within 48 hours, was using light oil on bearing to stop a squeak. Already. Not a good start for this R2 product.

Hello Allan,  Thank you for your purchase and for writing a review.  We are glad that you liked the product review information that we provide on our website.  It is good to know that customers are using our work.  Hobart King, Owner / Manager, RockTumbler.com

Hello Allan, I am responding to the addition to your review about needing oil to stop a squeak.  The tumblers are not oiled at the factory before they are sealed into retail packaging.  Most will run little noise during the first batch of rocks, but a few squeak before then.  But, after you finish the first batch of rocks, it is recommended that you do a complete lubrication after every batch of rocks or after every thirty days.  

We have a guide to lubricating Thumler's Tumblers here...

Why Trust Verified Reviews?

Verified Reviews are real, authentic reviews collected from actual paying customers, using Shopper Approved's Verified Review Platform. When reviews are Verified by Shopper Approved, you know that you can trust them to make better buying decisions.

Unverified Reviews on the other hand, are reviews collected by Open Review platforms that allow anyone to leave a review, without any validation or proof of purchase. Unfortunately, most reviews you read online are Unverified Reviews, and can't be trusted.

As a consumer, here's how you can tell the difference:

Verified Reviews from Verified Review Platforms like Shopper Approved, have much higher review counts and higher overall Star ratings, because they attempt to collect reviews from every single paying customer.

Unverified Reviews from Open Review Platforms, tend to have much lower review counts and more negative Star ratings, because people with bad experiences are primarily those who leave reviews. This often creates a misleading, inaccurate portrayal of a companies true reputation.

So, when searching for Verified Reviews, look for the name you know you can trust. Shopper Approved.
