Some have complained about losing belts every few days, which you can fix by a couple of simple adjustments. You can make the pully belt last by loosening and aligning the pulleys so that the belt is exactly aligned between them and then adjusting the belt tension to "almost" too loose, however the real problem with this product is that when tumbling normally, the dual drums like to move toward the edge of the tumbler and grind into the plastic tabs that are supposed to prevent this. This continuous friction causes the black plastic tabs to decay into nothing within a very short number of days. Then you get metal on metal grinding as the drum rotates against the metal frame and start self-destructing. Also plastic on the rollers starts to "shift" the other way and gets pushed into the bearings because the drum cannot move any further. Imminent failure...
Basically these tumblers self-destruct from just spinning. I purchased two of them and both ground down the plastic tabs, one in just a week. If I just run ONE drum instead of two drums, the one drum tends to migrate to the center of the rollers and not contact the edges/tabs. That's not great since the whole point was to tumble with both drums at once.
I returned one HF Dual Drum Tumbler already, just waiting for the other one to finally fail as well. :(
I'm replacing them with "Tumble-Bee Tumblers" dual-drum & single larger drum tumblers which have a better belt system and a well designed drum guide -- the knobs on the drums ride in a U-shaped metal slots that guide them. You could also step up to Lortone or Thumblers competing products. Spend a bit more and get a better product that won't fail very quickly and waste your time.
I learned from the start to give the unit a quick double check on the pulleys used to operate it, sometimes they are not true..Once adjusted though the belt will last a very (6 months) long time..Thats the only problem with these units..I also found a quick fix with a rubber band when the belt does break..Even a vacuum cleaner belt is a great replacement.
Keep the bushings oiled and it will outlast the thumblers version..
Keep the stones rolling.
The quality of the barrel pieces is lower than Lortone, but since it's half the price, I expected that. The rubber barrel appears to be the same as the one on my Lortone, but the lids are much lower quality. Rubber gasket on the lid is not attached, and you have to be very careful putting it on to not rip the rubber. The lid on the CE barrels also have a slight leak if you do not thoroughly clean it every time. Again, this is all covered in the instructions, so read them. With proper care I think it will be fine, but it cannot take the rough handling of a Lortone.
The reason I did not give it five stars is that it tumbles at a slower place than the Lortone. Since the whole point of tumbling is to get movement, a slower speed will mean longer polishing times. So far it seems to add about a day to each batch of rocks (one harder agate, one softer rhyolitic tuff/wonderstone), compared to Lortone brand.

This tumbler lasted 9 days of tumbling and then quit. It did not even make it through one complete cycle of rocks which takes a total of 3 to 4 weeks of tumbling. Read morePublished 6 days ago by Meredith Andrea Luce
One star ONLY because it's just beginning its polishing cycle and I can't rate it yet. It's a shared (2 grandchildren) tumbler, so the dual chambers are a perfect squabbling... Read morePublished 9 days ago by Scoobie Lane
