Title: Don't waste your money!
Review: My son had been wanting a tumbler for months and finally got one as a Christmas present, ordered from Amazon. First, it's confusing as to what company actually made this tumbler. It looks exactly like this one, but says it is by Science Tech. However, there are no tumblers on Amazon that say they are from Science Tech and this is the tumbler that comes up if you search for "Science Tech rock tumbler." Anyway, the tumbler worked well for the first set of rocks. However, during step 2 of the second set of rocks, the tumbler started leaking. We tried numerous times to patch it, but it didn't work. I've sent numerous emails to the company, but have not gotten any response. My recommendation - save yourself some money and buy another product!
