Customer Reviews

suggest pay more for a semi-pro unit
I bought this unit for my 9-year old daughter. It was easy to use but extremely loud. We live in an apartment and I was worried I was disturbing the neighbors - it really was that loud. It also burned out during the third tumbling step- we probably overloaded it, which is easy to do. I then bought a Lortone tumbler, which was about twice the price of this tumbler (sold on many web sites). However, what a pleasure to use. It has a rubber liner and tumbles so quietly it sound like a day at the ocean. We have tumbled several batches of rocks with the Lortone tumbler with no problems. I suggest ponying up the extra money if noise and durability are important to you.

Discovery Rock Tumbler Review - 35 Yr Old Mother
I bought this tumbler for my 7-year-old daughter. She has enjoyed using it more than I have. It does its job well for the price you pay. Be sure to read the directions carefully before starting. It is a very noisy and time-consuming activity. Each of the 4 steps takes a half-hour or less of your time. However, you must be a patient person because after every step, the rocks have to tumble for 2-7 days. You will need a room outside of your house to set it up in. We can still hear it in our detached guestroom from the patio. I loved witnessing the transformation process. I will be buying the refill because she is absolutely thrilled with her accomplishment.

Cool but noisy
This is a very cool gadget. The rocks were changed into pretty stones in under 3 weeks. This thing is VERY LOUD though. We had to keep it in the garage, and you could still hear it. This was a Christmas gift for the kids, but there is a lot involved, so it turned into a gift for my husband instead.

Finding replacement materials may be difficult. The Discovery online store is not expecting any for months, and the store here doesn't carry it.
