Comments about Product: It works beautifully. We have the first batch of rocks completely polished and have the 2nd batch going now. It does take almost a month to polish a batch of rocks, which surprised me. But the results are worth it :)
Comments about Product: I bought this for an 8 year old for his Birthday. This is an authentic rock polisher! It teaches that anything worth doing is worth waiting for! It does run 24/7 for several weeks and does make a little noise, but we are having a great deal of fun with it!
