    • Rock Tumbler was a hit!
      Verified Purchase

      My daughter has a small jewelry making business and wanted this to expand her line. She is loving it so far! It does a good job with the stones she has collected.

    • coin cleaner
      Verified Purchase

      My hobby is metal detecting. I use the tumbler to clean the coins that I dig up and that are not of collection value. The banks won't take a bag of dark coins. I use plain sand and it works great. For collectable copper pennies I use coffee grounds. This cleans them but leaves the patina intact. Before this I used a shell casing tumbler which was much sturdier but this machine is more a childs toy but it does the job and coasts much less.

      Verified Purchase

      Purchased this for as a gift for my son. Although it is a bit small he loves it and it has been running since Christmas day. I would recommend it to anyone who has a rock hound in their house.

      Broke after a month, very messy, hard to use, but you can't do much ice you've use it.

    • Cheap
      Verified Purchase

      You get what you pay for. Followed every instruction to a T, but cheap parts mean crazy amounts of mucky water will get all over whatever you place this rock tumbler on. Would not buy this again. Complete waste of money

    • So far so good
      Verified Purchase

      I've had this tumbler tumbling for about 2 weeks or so, working just fine. I originally purchased as a Xmas present for my grandchild, who is almost 9. I decided to keep it and let all my grandchildren enjoy the results, without the noise and the electrical hazard issues. I'm retired and have more time to help with the tumbler, plus I can put it in my unfinished basement, out of the way, and in a cooler to lessen the noise. The tumbler is pretty small, so can be used with small rocks. I think the kids will really enjoy the results...in another 2-3 weeks.
