We got this for my daughter's dorm room to make moving her large size mini fridge. For that purpose it works well. We did not attach the leveling feet because they don't retract enough if you want to be able to use this like a moving dolly. The bearings in the casters aren't exactly smooth. I tried lubricating them but this didn't make much difference. They should still rotate good enough to get the job done though. I like the ease of adjustment because it is 100% tool less. The bubble levels are not needed in my application but are a nice option for someone who needed to level whatever they placed on this. But they are not super visible. For a moderate weight application this should be fine. Not sure about something as heavy as a full size washer or dryer though.
