Product review (5 stars): All Good
Went with the brand by recommendation of a colleague; found it through Amazon at an incredible price; manufacturer called within an hour of the order to acknowledge order and verify delivery options (no extra charge). Arrived fast. Been up and running with no problems at all. There is substantial vacuum resistance when opening the door. On a tile floor we put the unit (casters) on caster pads to keep it from sliding forward while opening the door. (Locked casters kept the wheels from rolling, but they would still slide on the smooth floor - caster pads took care of the problem.)
