Arrived unwrapped.
4 out of 5 stars
Arrived unwrapped.
Its a great present for kids/adults. However, I have complain, my son wanted this for a long time, I hesitated as its not cheap. I decided to get it for him as a Christmas present. It came in original package, unwrapped, my son who was coming home from a swim lesson grabbed it from the mailman and ran excited into the house as you can see on our front door camera. It surely made him happy but two months prior to Christmas. I wish it was wrapped so you wouldn't see the content.
Thank you for your feedback

    Ranked right up there with hover board. Not my opinion but that of 8 year old grandson. Quality product. Complete ready to use. Easy to use. Set up in garage as it is noisy and must run 24 hours for many days. Fantastic learning tool including learning patience as it takes about a month from start to finish. Worth the wait and effort. Beautiful results.

    My son bought this with an Amazon gift card. He's ten and loves rocks, gems, Geology, etc. This came with a bunch of rough gems he's been tumbling for days. He loves it. A few things to consider: it has to run for days at a time in order to really smooth the gems, and it can be pretty messy. Otherwise it shipped fast and is what I expected.

    Worked perfectly and the whole family enjoys. Every week we check the stones and use the next packet. For Christmas we’re using the stones we made as gifts for family and friends. We put upstairs but it’s not extremely loud. Something we will definitely keep and use for years.

    This is my first rock tumbler. I was expecting it to be loud, but it is not. It is about as loud as a washing machine when it is in the wash cycle.
    It works as described, and I have been pleased with the results that I have seen so far. The tumbler came with unpolished rocks of various types and a booklet explaining the characteristics of the rocks, as well as where they are found from around the world.
    My first polishing run is in its final stage, so I haven’t yet seen the “end product”, but I definitely noticed the rocks looked a lot better than when I put them into the tumbler. I can’t wait to see the final results in a few days.
    If you even have the slightest interest in rocks, then I would recommend this rock tumbler.

    I am very happy with my rock tumbler, I have collected rocks since I was a child, mostly agates but now I wil be able to make pretty rocks even more beautiful! The only downfall is that after living in a house for 12 years I now live in an apartment so I'll need to see where I can set up at my mom's home which will make it a bit more of a challenge but I will find a way to make my beach treasures even more beautiful, I have always wanted a tumbler and this is the perfect tumbler to learn how to do my new hobby. This is the perfect machine to learn how to start my new hobby and make my treasures exactly that, treasures !

    I bought this rock tumbler on January 17th, 2020, delayed using it for a few weeks, then set it up for phase 1 - (speed 1 for three days). When I went to set the tumbler to phase 2 (speed two for 6 days), the machine stops turning and displayed an error message. I did not overload the tumbler barrel.

    This product is two months out of the box and in use for three days and it doesn't work. Unfortunately, the model I bought is no longer for sale (the 'professional'version) AND there is no way to follow thru with the two year unconditional warranty. The sales page clearly advertises the warranty but there is no information included in the box and Amazon will not allow me to write to Nat Geo Toys to follow up.

    This product seemed like it would be great, and I cannot understand how the motor failed in such a short period of time when it is never under serious load.

    I’ve been using my tumbler for several months now and it is working wonderfully. I bought the professional one and recommend that one. I like the option of setting how many days to run and setting the speed of rotation. The tumbler is in my utility room and it’s not as noisy as I was expecting. The rubber barrel helps muffle the noise.
    I have tumbled picture jasper, petrified wood, and the mix included in the kit with great results. Just follow the directions, research online, and be patient! :)

    Just finished my first batch of tumbled stones. They went in looking pretty rough, sharp edges, poir color, no shine. But came out amazing! Beautiful colors, high shine, no sharp edgrs. Perfect for collectors or making jewelry.

    The tumbler itself is fairly quiet, but I found adding a little more water helps keep the noise level down. It's so easy to use. I have my second batch in now and can't wait to see how they turn out.

    Reviewed in Australia on May 22, 2020
    Got this for myself (37M) and really pleased so far. I have started the process with some of the rocks that came with it along with some of my un-polished collection i have picked up around the place (even a few from the rock pathway to see what happens to them).

    The rubber barrel construction feels and looks great and does its job of absorbing the noise. I have it going in the spare room with the door closed and can't hear it unless i strain my ears.

    Very pleased with it and can't wait to see the stones finished.
