Every maker has a defect that passes through QC now and then. Cabela's will replace the unit.
I have a total of THREE of these tumblers, Berry's and Cabela's, and I run them nearly continuously during brass season for weeks and months at a time.
I had ONE fail ONCE....and it was my fault- I was trying some bulk crushed walnut bedding from Kaytee (Never buying that again, too much dust!) I left the lid loose, and dust and media got into the motor due to the cooling fan. Ran fine until I shut it off to empty it, then would not start up. Took it outside, blew it out, put some 3-in-1 oil on the bearings, and it took right off and hasn't missed a beat- and that was three years ago.
By way of comparison I have eaten the motors out of a Midway 1292, a Frankford Arsenal and a Lyman Turbo 1200 in less than a year. That Midway 1292 I went through three bowls (one because the cat knocked it off the table).
The Frankford Arsenal was really disappointing. Thin motor shaft, small bearings, no cooling slots in the base, and it went quick. I would rather have the Harbor Freight than another one of them. The motor's rotor ate downwards through the bearings (not thrust bearings, just sleeve) and then ate the zinc end plate and literally fell out the bottom of the frame. I needed one now and it was in stock at the store. My fault for thinking it was anything more than a cheapie.
The cheapest tumbler (other than the Berry's/Cabela's) that impressed me? The Harbor Freight 5-pound job that's the same size as the Frankford Arsenal. Totally different motor design. Same bowls as Midway 1292. Noisy, like machine-shop noisy, but it works. The center threaded shaft (It's actually a long bolt) where the wing nut goes is soft and strips the threads or stretches after a lot of use so a piece of good made-in-USA allthread and some nuts and lockwashers is in order.
Bear in mind that I am basically a commercial tumbler user, so the average guy who tumbles a few times a month for an hour or two isn't going to see the same accelerated wear I see.
