I needed to mix concrete for a pad that would use 17 bags (60 pounders) in one pouring. The mixer arrived boxed in a manner that made assembly easy and kept the contents in good shape in spite of what was clearly a long shipping journey. The video provided by the seller, plus the printed instructions, made the process very straight forward and I was able to do it myself with no problems. All of the fasteners and small parts are bagged and each bag is lettered and corresponds to an assembly step. The only thing I opted to add was when putting the rotating parts together, I took that sub-assembly opportunity to add heavy grease to the bearing sleeves. When it came time to mix, I made sure the mixer was on level ground. I mixed two sixty-pound bags at a time and the motor was plenty strong enough to rotate the drum at all the different angles needed. It could have taken one more bag, but that would seem to me to be pushing things a lot closer to the limit of the unit. The volume of the drum is only just sufficient for 180 pounds of pre-mix, so pouring it out from that full a volume could get sloppy if using a wheel barrow as I was. If the mixer were in the pour area and could direct discharge into the form, then I would say it would be fine. I used a stiff mix (minimal water added) and that puts a lot of stress on the frame as the batch with tend to cling then slump to the drum as it rotates-- frame held up fine. I took each bag and (motor off) put it on the top of the upgright drum and then trowel cut the bag to dump it into the drum, frame was steady. I would then start the motor, which pitched right in, and when rotating then move the angle of the drum to where I wanted it for adding water. Motor was warm at the end, but still comfortable to the touch. Buttons are sealed to keep out debris. The drive gear is well protected from concrete splash. The powder coat finish is a major plus in keeping things easy to hose off and clean up. It is not something for weekly use, but for homeowner demands, it does a surprisingly good job and when you need the labor savings and speed of a mixer, it is great to have. It also works great for dry-mixing animal feed. Everything hoses down easily for final cleanup.
