Review: Three Days Strong - The tumbler was super easy to set up, the included polish was a wonderful addition although I'll need to buy more to use again. We used a gram scale to measure the amount we put inside, we followed the weight limit the instructions included and we haven't had the band break. I know a lot of people mentioned that, so we are hopeful the weight limit kept that in mind. So far so good, no leaks, no issues functioning and the rocks are coming along nicely. A good cheap tumbler. It is a little noisy but we keep it in the garage and that solves the issue! If you're looking for something to polish your stones it's a nice small size and performs great, tumblers take a long time anyway so the fact it stays together and rolls is all we need!
Review: Update! Motor Won't Run - Update: The seller reached out and refunded my order. We purchased a new unit and all works perfectly! I recommend this product and seller. I purchased this for my daughter for Christmas. Right out of the box, the motor will not spin for more than a second. There isn't enough torque to spin anything. Unfortunately the return window was very short so I am stuck with a broken unit and disappointed child. Update: after looking closer, I feel this unit was a used return and resold as new.
