I’m on Stage 4 now and the bag of rocks I got as part of the kit now amount to 14 stones with the smallest being 0.5cmx0.5cm. The rest are pretty much grit.
Will update when full cycle complete.
Fun while it lasted. Unfortunately the motor has burnt out after 9 months. I’m hopeful nat geo will help me out here.
Edit: Nat geo came through and sent me a new one out.
Please though, this isn’t a toy for a 5 year old, buy them something to push around the garden or a dolls house or a train set. No child of mine was ever going to find any sort of thrill in a stone tumbler that did nothing but turn around for 4-6 weeks and produce shiny stones until they were teenagers. Please be realistic. It doesn’t mean it’s not a good product. Yes of course it makes a noise, it has stones tumbling around inside it, what do you expect. Stick it in the garage or in a cupboard if it’s a problem for you .
A great little machine.
So far this product has lived up to it, it’s been going none stop since the day I had it, I’m on my 3rd step and it’s still going, my only fault with it is, I’m too nosy an impatient, I like to see how my stone are going half way through, when I stop it, it takes it back to day 1, all I do is start it back up by the day I was on, but I do love it, will be doing my own rocks as I live by the beach, so happy days for me
Great build quality and easy to follow instructions for children.
his product only lasted 6 months was great while it lasted , but expensive for how long it last.
Have done one session of polishing. Takes a fair amount of time, but results are worth it.
A very long process so patience is a must. But produces lovely shiny smooth stones. I would recommend putting this somewhere you don’t go often when it’s on. It’s not incredibly loud but the noise becomes very annoying when it’s on constantly for days.
Perfect for children to learn about stones, how they are polished using other stones, grit, sand etc. Great little kit with little sample rocks plus all the materials to polish them with. Great present and one happy little boy!
I bought this for my wife’s birthday three weeks ago and its been running almost nonstop ever since. A really good starter set for rock tumbling, it has everything you need to get going. The only thing to consider is that it can be quick loud when running, but you’re tumbling rocks, it was never going to be quiet.
The product works but be aware that it needs to stay on 24 hours a day for 3 to 4 weeks to complete a cycle and it is noisy so if you don’t have a room far away with a socket I would not recommend it. On the other hand I must say it does work and the stones look great.
I had an issue with mine after about 3 weeks, I contacted them on the Friday afternoon and by 11am on Sunday I had a brand new one in my hands.
It’s quiet, cheap to run and it does the job very well.
I’ll be purchasing more in the future!!
Bought for Christmas present and have not used yet. The machine looks good quality and well made.
Takes longer than expected to get the desired results but everything you need is in the kit.
