Poor:
I bought 2 of these one for myself and one for my grandaughter, both have stopped within the 2nd step and required alot of re-starts. It is also makes so much noise you can hear it throughout our home.

Should come with ear plugs!:
Don't buy this for a child unless you want to be hated by the parents. It's noisy, takes days to work, and the chemicals it comes with stain carpets forever. I don't know who could stand to listen to this thing running for the over 24 hours it recommends.

Great rock tumbler!:
I bought this for my daughter for christmas and she loves it. It says it will take a total of 2 to 4 weeks to complete the stones, but all rock tumblers will. It is good quality, a cool design, and easy instructions. Yes, it is loud, but it is not the machine that is loud, it is the rocks being tossed around, so how could it not be loud, that is the point of a tumbler. We just put her rock tumbler in the bathroom in the basement and threw a towel over it to muffle the noise. Even after just 3 days of tumbling the stones are already starting to take shape. And the rocks that they send with the kit are very cool looking turquoise and tiger's eye. The kit only comes with 1 packet of each step of grits and polishes, so you can only polish one batch of rocks, but you can get another brand refill Grit Pack for #130 or #140 with enough grits and polish to do 8 more batchs for very cheap, so I ordered that to refill.

Prepare for noise and 3 weeks of waiting:
I can't say this is a bad product. If you have a shed in your backyard (too loud for the garage even!) with electricity, and about 15-20 days of patience with a little "work" in-between the four stages this is alright. The work is actually the fun part. Changing the different powders inside and seeing the progress you are making. (also the tumbler needs cleaning after every step..but I imagine this would be true with any tumbler). My son and I have successfully completed 1 batch of rocks and are half way through our second batch. No instant "fun" with this product, but satisfaction if you make it through round 1.

Requires Patience and Preserverence:
I had been told it requires a lot of time to polish rocks. I had no idea that in addition to the time there are multiple checks, drains and refills to complete a batch of small stones (the tumbler only works on pebble size stones). Only give this to someone with the patience and perserverence to follow the process through a week or more. I will say the stones are really polished at the end of the cycle. The polisher is really loud. We had to put it in the garage so we could sleep. Also note that the tumbler only comes with enough materials for 1-2 tumbling cycles. Then you need to order more polishing powder. The instructions say you should NOT put the liquid from the tubler into your home plumbing.
