What a Gem!

Reviewed in Australia on 30 August 2020

I bought the tumbler for my 7 year old but have had more fun than him. Running it near constant for a month has been no issue at all with the exception of the noise. The noise comes from the rocks tumbling, not the machine. I highly recommend building a box for it and filling lining the inside with foam to heap deaden the noise, then put it in a garage. That's what I did and I only hear it when I go in there. You get used to the noise but it is noticeably quiet when it gets switched off after a month. The safety features such as cut off it fingers are caught in the rollers are great, not that it is any concern as it is only the weight of the rocks. I highly recommend it but be prepared to find your own rocks and grit after.

Not satisfied as it trips out.

Reviewed in Australia on 23 August 2021

It's tripping into fault mode and I cannot find a return address to get my refund. I am looking for a friend to assist me as return system is too difficult to work out. I guess I will be stuck with it till then.

I bought this for my bff cause she’s crystal and gem crazy and she loved it. Wasn’t excited about how long it took lol but she loved what she got and is excited to use it more. The stones she got was pretty big and most were really nice pieces overall.

I use for cleaning jewelry and the rubber is not great for this

Fine for metal but not great for my crystals the black rubber stains crystals. I just the tumbler base with a mason jar and that works but would have gotten a different tumbler if I had know the rubber would breakdown and stain my pieces.

Surprisingly quite

So I know rock tumblers are loud and I expected that but I was able to put this on in a closet and can barely hear it when im in the room with it. It's there I can hear it but if I'm not listening for it it's almost like white noise. I can turn my fan on and its drowned out completely which is fantastic. I'm still working in my first batch of crystals but I'm excited to see how they turn out once it's done. Super happy with this product

Was noisy, but tolerable since we used it on the porch. My grandkids are really into gems, crystals and rocks so they are really enjoying it.

DOES NOT LEAK IF YOU READ THE INSTRUCTIONS

I LOVE IT. This is a great product and does exactly what it should. Comes with a good variety of KNOWN crystals. Only thing I didn’t like was that it only comes with enough grit to tumble one batch fully. I will definitely be using this 24/7

Didn't do a very good job of shining the beach stones that I had

Didn't do a very good job of shining the beach stones that I had. I haven't tried it with the stones/ crystals that came with it yet.
It does seem to be good quality, I have ran it for over 30 non stop hours without any problems
