## Customer Reviews

### ⭐⭐⭐⭐⭐ Powerful motor. 3 pound barrel. My favorite tumbler.
*by S***H on February 13, 2023*

I have several rock tumblers and this is the most reliable and highest quality of the bunch. It has no problem turning a heavy barrel that bring my other tumblers to a halt. This is a pricier model and you can get two cheap tumblers for the price of this one. If you are buying for a young child and suspect they will lose interest after a few batches, you might not need this tumbler. Otherwise, I think this tumbler is a great way to go. Keep in mind, this is made of plastic and not indestructible. The huge metal professional tumblers cost about $1k. There are tumblers with metal housings around this price, which may be more outwardly durable. They are a good choice if your kids plan on throwing their rock tumbler off a roof. I had a rock tumbler of that style and it only lasted for a few batches and died. Others said they short circuit and could cause fires. Kids who throw rock tumblers off roofs may like a bit of pyrotechnics, but since most of us leave our tumblers unsupervised in garages and basements, the fire hazard is a deal breaker. Those tumblers also don’t have multiple speeds or a timer. TL/DR. This is the best tumbler in this price range.

### ⭐⭐⭐⭐⭐ It’s a good tumbler and not very expensive. I will buy another 👍🏽
*by L***Y on April 11, 2025*

Awesome rock tumbler. I love it. The best one I’ve used yet. I love the large 3lb barrel. Haven’t missed a beat I’ve been running it since I got it and the belt that came on it is still rocking and rolling it’s been almost 2 months. AWESOME!!!!

### ⭐⭐⭐⭐ Good tumbler but belts need improvement
*by J***R on March 9, 2023*

On the one I purchased, the belt broke after 2 weeks. Put on the replacement belt (included) and it broke as well after 3 weeks. Contacted seller and to my surprise, they didn't send a replacement belt, they sent an entire new tumbler so now i have two of these. The belts on Amazon are pricy, about $17 each. I went to my local ACE Hardware store and bought a "medium O-ring assortment kit" for $7 which includes 6 rubber o-rings, at least 4 of which will fit the tumbler. Problem solved! I also purchased a spray can of rubber belt treatment/conditioner at O'Reilly auto parts to spray on the O-rings. Aside from the belt issue, this is a great little tumbler which I believe the o-ring solution should work just fine. Very pleased!
