      This works great and isn't all that loud (I keep it in the garage). The instructions are very vague, so here are some tips. The water...put enough water in the tumbler to cover the rocks, etc., along with the grit. After a week of running for 24 hours, check your rocks for desired smoothness. When ready, clean the rocks (water) and clean the tumbler thoroughly. DO NOT do this in sinks, the grit will clog your drains, like cement was poured into them. Always put a slight amount of cooking oil around the inner cap and around the lip of the tumbler (the instructions for this come with your purchase). Repeat the water process with the rocks 2nd stage of grit. Wait a week, but tumble these 24 hours a day. Check the rocks for desired smoothness and repeat cleaning process, start all over with the next grit. The 4th step, the polish. Run for a week @ 24 hours. If you would like the rocks, etc., to be even shinier and better polished, clean out the tumbler and add about 1/4 cup of Ivory Bar Soap. You need to make the pieces shredded, like shredded cheese. Run until desired shine is achieved. Be patient, this process from start to finish, takes at least a month. Have fun and enjoy!

      I'm done with overstock after this! It came in missing the barrel for the tumbler! The gift was sent home with my in-laws so I don't even have the ability to ship it back.

      My son loves rocks so we tumbled ones he'd collected. Great product with a great outcome of beautiful shiny rocks. And we will have fun tumbling the ones included.

      I bought this for my granddaughter. She is so happy to have gotten it. She's a little disappointed that it takes as long as it does for the process of polishing the rocks. But other then that she is happy
