Assembling the unit was easy although the instructions left a lot to be desired. Parts list stated that split locking washers were included for the caster wheels when standard flat washers were actually in the hardware kit. I have a small shop so I thought this would be perfect to wheel around to the few pieces of equipment I have. I started using it after reading the instructions. I used it on my table saw, planer and planer joiner. The results for my table saw were poor. Perhaps my table saw is too big for this dust collector. I got excellent results on my planer and planer joiner. The dust collector is relatively quiet. I wished it had a support system for the bag to keep it up off of the floor. Overall not a bad investment.
