TUMBLER is a piece of JUNK !
charlie badger•October 10, 2017
Wanted to return this product but beyond return time. Started using it with my granddaughter a week [September 30, 2017 ago as I had not seen her since August and has much helpful information in package. Requires about 30 days to complete tumbler cycle. Worked fine for phase one , then per instructions, cleaned rocks, changed water and it started to tumble then stoped, tightened lid-same result, Never got further as it stopped working . May contact manufacturer if I still have information as the machine I was sent is a piece of junk that did not even surrvive the tumbling cycle.
Product worked beautifully the first time but then broke after the second ...

Product worked beautifully the first time but then broke after the second time. My son was very disappointed and there was no way for me to contact the seller to order a replacement.

Pretty much garbage...thing leaked grit from day one and rocks do NOT polish as advertised even after 2 weeks of tumbling.
