5.0 out of 5 stars Turn those rough little stones into gems!
By Taylor - Lincoln City OR on January 19, 2020
I bought the rock tumbler for the wife for Christmas. We moved to the beach where she finds agates and other pretty little prizes. Pictured is her first batch after the 3rd week. We rinsed and put in the 4th packet. The tumbler works well and have no issues. This is turning into a fun little hobby for her.

Update 6/7/20 Tumbler still going strong!

4.0 out of 5 stars Good so far....
By Mamabb18 on June 30, 2019
Little noisy —thought it would be more quiet. Oh’ well, I’m okay w that. Might have to move it to the garage, if it’s too loud at night. Bought for our daughter for her 9th bday. She’s obsessed with rocks.:) Took before pic and will take an after pic in 5 days when they’re done!!

Update: Turned out okay. Four days in the spinner with a level ‘four’ grit, and not much of a change to the rocks certainly not shiny rocks. Daughter kept saying she liked the rocks, before..

Life is too short to waste time on writing reviews for all Amazon items but in this case.....

See photo, power supply transformer exploded peppering my daughter with electrical components! This is not fit for sale! Over to you Amazon - remove it from sale before someone gets hurt.

My daughter has wanted a rock tumbler for ages and so got this for her Birthday. She was just coming to the end of the first 4 week cycle when the thing malfunctioned spectacularly.

Reviewed in the United Kingdom on January 26, 2020
So far I'm not impressed by this, ours arrived with a tumbler that is different to the pictures as it has a metal cap on the opposite end to the filling cap, this metal cap runs on the plastic rollers creating horrific noise and is already creating wear and bits of plastic. I dont know if the metal cap is a new addition or not but it appears to be glued in place. If it wasnt fir this I would give 5 stars

5.0 out of 5 stars A refund for faulty equipment required.
Reviewed in the United Kingdom on August 14, 2020
Faulty Advanced Professional Tumbler purchased and received by 7th August 2020. When I went to check on the tumbler which had been on for 6 days on setting 2 speed and medium size grit to find that the tumbler barrel has blown up like a balloon. I immediately switched it off from the power and removed it from my garage and placed it in a box in the garden just incase it explodes. I can not send it back for it is too dangerous for me to handle. I am so disappointed that I can't see the stones that have been tumbled so far. I wish for a refund as I am not wishing to use or proceed with the rock tumbling experience for it has made me scared of what could have happened if it had exploded? Please can you refund me for the tumbler machine. I can send the actual tumbler machine back if required but I won't send the barrel back for it hasn't had the pressure released and I'm not going near it whilst it is all blown up like a balloon. Please advise me on what to do to get a refund for the faulty equipment. Kind Regards E. Dyer.
