Barrel lid broke - updated

Reviewed in the United States 🇺🇸 on May 21, 2023

Verified Purchase

Lid of barrel broke on 6th batch of rocks. Lid started cross threading and when I went to reverse it to take it off the lid broke in two. Worked great but too much plastic on the lid makes it weak.

Update: seller refunded the full purchase price! Excellent customer service. They turned a bad experience into a good experience. Ty

Went well until it didn't

Reviewed in the United States 🇺🇸 on October 21, 2022

Now I was super excited to get this, after Amazon lost the first one, I reordered it on a whil because I have a lot of raw stones I wanted to tumble. Let me say the noise level is amazing, you can barely hear it when it running and I really appreciated that. It was super simple to set up and get running too! But..... The lid has given me multiple problems. It is doesn't want to screw on properly than it doesn't want to come off, the first time it happened I simply did as the instructions said and just ran it under hot water for a few seconds, came off well enough. But on the second cycle through with only a day left to a six day tumble I decided I wanted to see how the stones were looking and if I wanted to add a few more days. As of Friday 10-21 I have been trying for almost two HOURS to get the lid off. I have ran it under the hottest water my kitchen sink can make for ten seconds and then ten minutes. I have submerged it to try and loosen it up, in hot water. And it won't come off. I have tried prying the lid off with a fork KNOWING I will probably have to replace the stupid thing. Quite honestly the only thing left to do is take a knife and slice it open. Would I buy it again? No. Would I get it as a gift? Probably, and hope they get a better lid than I did. It was so nice until it wasn't.

Issues, but nice finished product

Reviewed in the United States 🇺🇸 on August 25, 2022

Verified Purchase

UPDATE- Nat geo contacted me about our issues and gave me some tips to try and alleviate them. No luck it just seemed the motor was weak on the "A" polish speed. Megan in customer service at that point offered to replace our unit. On that note I upped my rating to 4 stars and if the new unit works better it will go to 5 because, even with the issues, we are more than pleased with the final product. with this type of customer support, we will be buying more products from Nat geo in the future. -

We had very high hopes for this and very let down a little. We purchased this tumbler for the natgeo name. The tank will leak if it is not secured tightly, seems obvious, but when I say tight, I used a pipe wrench to stop the leaking. issue solved then came the constant stopping during cycles. it would go for a few hours or even a whole day and then stop with time remaining. this is a particular issue on the polishing speed of back and forth. On that speed it will not go even an hour without stopping. Tried to call tech support to no avail. On my own have figured some work arounds like making sure it is sitting slightly forward so the tub will not rub on the back wall and not using the "A" speed at all, so it takes time and patience, but it is really quiet and produces some really nicely polished stones. We also ordered the Natgeo grit pack #'s 1-4.

The screw-top barrel lid is a terrible design flaw!

Reviewed in the United States 🇺🇸 on March 25, 2023

Verified Purchase

The screw-on barrel lid is a serious design flaw. I had the hardest time getting the lid to seat properly, then it was almost impossible to remove after the cycle had completed. I made sure to clean it well (with a toothbrush to get all the grit out!) and set it for the 2nd cycle. Same problem ... the lid was terribly difficult to unscrew, even with pouring hot water on it, tapping the sides, putting it into the freezer.

I finally solved the problem ... I bought a Lortone 33B tumbler and I couldn't be happier! It is worth the extra money and a wonderful tumbler. Highly recommend it. I'll see if I can purchase a new barrel for this NG tumbler and will give it a second chance but right now would NOT recommend it.

Can't finish the job

Reviewed in the United States 🇺🇸 on April 1, 2023

Verified Purchase

I took up rock tumbling a couple years ago. I had another tumbler and decided to upgrade to this one, especially because it has the cover to lessen the noise. I was able to get some good results for the first batch. After that, when it was time to go to step 4, it stopped working. I followed the instructions closely and it is still broken and sitting on my bathroom shelf. I will be getting a new one, I guess, and hoping it won't go the way of its brother. It will be great if and when I can actually see the finished rocks from Step 4.
