Just got this yesterday and have already used it with ball bearings to clean old dirty copper coins i find metal detecting....and I use a bit of white vinegar, teaspoon of baking soda, water and steel ball bearings and then let it tumble away for 30 mins and the coins come up amazing. The only thin the next model has option to select how many days you want it to run for. BUT, who really wants it to run when your out if it's in the house or your in bed? Too risky IMHO...so don't pay the extra £20 for next model up...this kit is awesiome. Comes with small siv, lots of unpolished rocks to get you started and 4 packets of different coarse grit, for your rock/gemstones etc. + VERY well laid out instructions and info.
Purchased kit in July for a Christmas gift. Went to set it up after Christmas and it wouldn’t turn on. Called Amazon but because I purchased it 5 months ago they could not offer a refund or replacement, which I understand. I then called National Geographic directly from the number on the box. Their customer service was AMAZING! They are not only sending a replacement kit but have also upgraded it as well. I’m super happy with the customer service from National Geographic. Thank you to both parties.
Gift for my 12yr old daughter. She is very happy with this tumbler, and I'm happy that it's nowhere near as noisy as I was expecting it to be! It's set up in the utility room, and when the door is shut it's hardly noticeable, especially with normal household noise. She started the tumbling process pretty much as soon as she opened it, and can't wait to see the finished product - though obviously, she WILL have to wait, as to get the best results takes a LONG time (around 4 weeks or so if you follow the recommendations in the leaflet to the letter - so might not be the best gift for an impatient child!) After two days of tumbling with the #1 grit, we are already seeing some good results from the original rough stones. I like the fact that there is the option to use some of the finished stones with the jewellery and keyring mounts included in the pack.
I will review again after I have finished the process of polishing stones roughly one month from now, as can be expected this is quite noisy so I would suggest finding some where to put it like a garage or if you live in a flat like me switching it off of a night, this will extend the process quite a bit but if you like peaceful nights sleep I would recommend it. there are are four forms of grit supplied for the first experiment, Course, Medium, Fine and polish, I am currently on stage two Medium, I was surprised even after stage one how smooth and shiny the stones and crystal are, I am looking forward to seeing the final result in about ten days time.
Arrived on the correct day, albeit late evening. I got this for my young boys, oldest being 9 years (also allow me to have a 2nd childhood). We'd collected stones from a holiday just past with the theory of using these. However the rocks supplied are pretty nice and you know that they'll come up super, so we ended up using the supplied stones.
At the moment we've been running it for a week and have moved onto stage 2 (you have 5 stages to work through, so you are looking at a month or bit longer to complete the cycle of polishing your rocks/stones). So I can't really comment on how it fully turns out - however after the first cycle they really do start to shine. you do get some bits in the box to put it on a ring and necklace - so we are hoping to make some jewelry out of these, with the hope of flogging them to granny and aunt's to make some money back
You only get 5 sachets of grinding powder, so it will only do what is specified in the box - so if we want to continue with others, you'll need to look at purchasing more powder. I have saved the left overs from the grinding in a bottle - so might give that a go (who knows it might still work). the only downside to this is we have to switch it off over night, as we have a small house we can hear it running during the night - not an issue for us, if you've got a garage or shed with power - then it'll be no issue.
One of the best gifts I have ever bought for my daughter... She is 8 and very much into all kinds of rocks and crystals, she has quite a big collection of ready polished stones but now she enjoys tumbling them herself. She has even added some other stones and sea glass to the tumbler.
The tumbler comes with a good amount of raw rocks in the set but it does not really say how many of them to put inside the barrel in one go. We have added half of the rocks but then realized there is only one sachet of each type of the grit. Therefore once we're finished with each of the grits we have strained them through coffee filter papers and dried them out on the heater to save them for the second batch of the stones. It would be really useful if the set was coming with more grit or at least for it to be available separately to top-up. There are National Geographic tumbler refill packs that come with the grit but there are only two types of refills (gemstones or jaspers mix), and once you have all of the stones you want just grit alone, not the same rocks.
Keep in mind that the tumbling may take weeks, it took us 3 full days for the first grit to lose all the rough edges, 3-4 days for grit #2 and then 5 days for grit #3 and lastly another 5-6 days for the last fine grit. It all depends on the effect you want to achieve and the type of rocks, harder stones like the hematite take longer than rose quartz for instance.
Nevertheless, this is a great set, comes with everything needed to start tumbling the stones, there are even strainer and some jewelry findings included in the set to make use of the stones. Recommended.
It is a great starter kit, my intentions were to teach my grand children the beauty of rocks and how to make them into jewellery. I brought some pebbles back from a recent visit to Sutherland where I found them on a beach. They were placed in the Stone Tumble last night a few hours after the product arrived and having read the instructions. I checked them after 24 hours and the results are so far amazing. Looking forward to seeing them after complete process. Already thinking of getting a bigger model this one will be given to the wee ones to use. !0/10
This is a great gift that is completely different to normal. First thing to be aware of is that it takes a few weeks for the rocks to be fully tumbled and shined, so if you're looking for an immediate result this probably isn't for you. In a world full of apps and games it's nice to be able to take a piece of nature and turn it in to something beautiful. I would definitely recommend this product.
My initial product purchased wasn’t ‘man for the job’ but the Customer Service from National Geographic was incredible. They immediately sent me the hobby version of the tumbler at no extra cost and it is brilliant, just what I need. They do call this version a toy and it is so if you’re looking at it for a hobby, go to the next level up.
This is so much smaller the it shows and it’s all made of plastic . It’s ok for a beginner but it can only hold maybe 4 small rocks at a time and it’s so hard to open and close . Not very happy with it at all wish I would have tried a different one instead .
