    Awesome tumbler!

    This is awesome! It takes awhile for the rocks to go through the process (usually about 5-8 days per grit and there are 4 different grits). We are on the last grit for polishing. The stones already look amazing and I can't wait to see the finished product. We used all of the rocks that came with the kit as well as some stones from the beach. The next batch will be all beach rocks so it will be interesting to see how they turn out. Because of the rubber tub, the noise the tumbler makes is pretty quiet. We keep it in the basement of our home and sometimes I forget that it's there because it is so quiet.

    Fun project.

    I wasn't sure about the size when I first ordered. It is smaller then I thought but large enough to hold a small batch of rocks. I am new at rock tumbling and didn't realize it takes about a month of steady running and weekly changing the grit to get the end result. I am enjoying the process and the tumbler is very easy to run and very sturdy. I am happy with my purchase.

    Gem Fun

    I purchased the rock tumbler for my 9 year old grandson who loves mining for gems. He is thrilled with the tumbler for it polishes his gems making them more eye appealing. Great value too.

    cool

    it's a fun activity to do with your kids, but it only brings joy when you are filling it or opening it, the rest is just a noisy waiting game, so make sure you have where to put it, and be patient, also order extra grit kits you will need them eventually
