Lortone 3A Single Barrel Rock Tumbler Kit - Professional Stone Polisher for Jewelry Making & Lapidary Hobby - Perfect for Gemstones, Crystals & Rocks (Great Gift for Rock Collectors & DIY Crafters)

Overall a great little tumbler, for a hobbyist or someone that uses it once in a while! I see I need a much bigger one to do my projects. No leakage or problems of any kind so far. My only concern was, the motor does tend to get a little warm after about 8 hours. I did check on it during the night several times, just don't want to burn down the house! I tumbled my broken glass bottles and jars just 24 hours and I have to say I'm very pleased how the edges were rounded off with no sharp edges. So with that, I moved onto grit #2 and will check it in 24 hours. Maybe in a couple weeks or so, I will tumble some rough gemstones. About the noise, I consider it background noise, not that bad! But you wouldn't want it in your bedroom while sleeping. Follow the directions and don't overfill your barrel and everything will be ok! If your planning a very large project or you see it's an ongoing thing, I'd get a much bigger tumbler. Follow the directions and don't overfill your barrel and everything will be ok!
