I usually do not write such detailed reviews but due to my frustration with other tumblers felt compelled to do so after finally finding a decent and reasonable priced unit. I've owned numerous low price tumblers ($100 range ) and so far this tumbler has been my favorite. I've had Lortone, Dura-bull, and Thumbler's in both rotary and vibrator. All of these units in my experience had major problems with barrel leakage, slippage of drive mechanism and barrel wear. I have run this unit approximately 40 hours so far in 30 minute increments and here are my observations. At first I was skeptical of the ease of operating the lid, but I have found it far easier if for nothing else IT DOES NOT LEAK and requires no effort to keep it from leaking. The barrel has remained clear unlike a dura-bull barrel which clouded over immediately, and the drive process creates no wear on the lid. The unit has a very solid feel. The drive belt runs true without slipping. The drive rollers are teethed creating a slip free rotation of the barrel. The barrel has a durable orange rubber ring that contacts with the drive rollers and appears it will not wear easily. I love the timer feature and the multiple speed choice. For larger pieces that may hang up in the barrel, there is a reversing option that automatically stops and changes the direction of the barrel every 30 seconds or so. The noise level is equal or less than the other rotary tumblers (which squeaked a lot if not lubed). I do not see a need to lube this model as the roller shafts are concealed. Since it has not leaked or worn the barrel from slipping, there is no grime or buildup of worn rubber or plastic like on the above mentioned models. I have read the reviews on motor failure and the control knobs not feeling solid. I will revise my review if they become an issue but so far all is good. Replacement lid gasket and drive belt are included. After I get several hundred hours on this unit, I will definitely consider another unit for s
