Review on High-Capacity Aluminum Pneumatic Dollie: Magline HBK128HM4 by Brian Samuel

Ability to move six 5 gallon bottles over bumps/bumps and set cart upright in amazing mode. Edit: After several months of continuous use (200 bottles a day / 5 days a week) the brass bushings between the trays and the frame almost collapsed. I strongly recommend buying 6 brass washers, the inside diameter of which matches the outside diameter of the bushing. Also make sure the washers are slightly thicker than the bushings so the bolt rests on the washer and prevents the bushings from being compressed. The inside of the bushings is essential for the correct seating of the shells. You don't need to buy new bushings as they cost around $6 each. Nevertheless 5 stars.
