If it actually worked it would take almost a month till you get a finished product and the machine would need to stay on 24 hrs a day. The tumbler won't turn and it leaks so the water won't stay in it! I will be returning this for a refund!

Loved this rock tumbler! It took a little longer from start to finish then I thought it would but I loved the end result. I only did 2 days for each step and they came out awesome. I would recommend only putting semi similar stones and gems together though. Also I only used maybe 1/2 Tbsp of each powder.
