Tryes Rock Tumbler Kit Adults - Rock Polisher Tumbler with Noise Reduction Cover, Speed&Timer Control, Includes 4 Polishing Grits, Rough Gemstones, Learning Guide etc. Science Gift for All Ages(Blue)

I have been running this rock tumbler for about 3 weeks now and it's held up well. It hasn't leaked and it's done the job of shining and polishing my rocks. It is quiet because it has a lid

Nice tumbler and good price. Very quiet and does good job

I’m so happy I bought this. It arrived in great timing and received everything listed to start tumbling rocks. The instructions are easy to follow for a beginner and makes it simple to get started. It’s so much fun to see the progress on the rocks after every stage. My photo is the stones after stage 2 (before the final polishing stage). My tumbler has been running for days on the final stage and I haven’t had any issues with the machine.In the instruction booklet, they also list the stones they provide and some interesting information on each one.It’s an enjoyable hobby for children and adults!

i like the sound barrier, it might make it more bearable to dogs and to have around. its a gift, so i have no idea of its efficacy.

Bought as a Christmas gift and it has been going non-stop ever since. My daughter keeps it running in the basement and we've never been aware of any sounds coming from it. She loves showing us all the shiny rocks she has polished with it.

I purchased this for my 7 year old and he loves it. It isn't loud, doesn't shake the table ....not sure what I expected, but I was pleasantly surprised by this product. We just need to find out how to give his rocks a sheen.

I liked it while last, it was easy to use, and it did keep sound to minimal. But, after six months of use, it simply stopped working, no apparent reason to stop working it just did. So, for the value I paid, it is not worth it.

Bought for my kids for Christmas. Works excellent! Comes with everything you need to get started and love the sound muffling cover. Highly recommend
