Customer Reviews about Lortone 33B Rock Tumbler

There have been mixed reviews about the product. Where on one hand a lot of individuals have loved the features the Lortone 33B motor provides, other have found issues with prolonged usage.

  • A husband bought it for her wife who is a jewelry designer as a gift. She was happy with the functioning of the product. The usage was also not very extreme. She used only about 2 LBS of rocks to grind. It wasn’t long enough when the initially installed belt gave up on her and broke.

The Lortone team was very helpful in hearing her issues and providing a quick support.

  • Another customer had a hard time using the rock tumbler. He reviewed that although the functioning of the tumbler was good but when used optimally it heat up. Rather than using it in an enclosed atmosphere he took it out and had to stop work for the motors to cool down.

The heat up happens because of the pressure that’s put on the machine from grinding. It’s general, if extends for long, the Lortone customer service is always there.

Hope the review was helpful. I would suggest before buying a tumbler to check it’s specifications and your usage first. The Lortone 33B rock tumbler can a viable option only concern being budget.
