I like this set, although for very heavy pieces of furniture or other items, a second set of hands is still helpful. The furniture dolly metal bar comes in two pieces, which can be joined when needed, then taken apart when storing. The 360 degree moving wheels on each of the 4 mini dollies feel sturdy and like they would hold up well even after repeated use. The use of the metal bar still requires some bending over since it isn't very long after joining, but that may be for safety reasons. I like that I have this as an option for temporarily moving something or for longer term use, as I think I will put this under our heavy dehumidifier for long term use to aid in transporting the heavy bucket of water out on wheels. Overall, although this is convenient and helpful for one person, in my opinion if one has back issues, two people might be better suited for getting the wheeled mini dollies underneath the heavy item would be easier. Still, this works as it should and is certainly helpful for my use of gently rolling the heavy dehumidifier around. Thanks for reading.
