Upgraded 5-Wheel Heavy Duty Furniture Dolly - 1750kg/3858lbs Capacity, 360° Rotating Furniture Mover with 5 Wheels for Refrigerators, Sofas & Washing Machines - Perfect for Home Moving, Warehouse Relocation & Appliance Installation

I never can find anyone to help me with heavy things and I've lost a lot of strength as I've gotten older. I used these right away with a very heavy floor mirror. I couldn't even lift it half inch off the floor, so the jack that came with this lifted it right up and high enough to get the wheels under it. I held the mirror steady and started pushing it and it moved so easily, so smoothly. Wow, I can do this on my own again!This product "sort of" works, and I have been able to move a couple of heavy items with it. However, I had to stick small floor protectors on the bottom of the metal lock mechanisms. When the locks are disengages, the metal handles scrape the floor, and without protection on them, they will scratch the floor. A very poor design.Product looks great with that price. Wonder these wheels are small, but it lifts up to 2800 pounds. I do have a few heavy equipments weight 1800-2580 pounds. My question is each dolly can hold 700 lbs or 2800 lbs (3 small plastic wheels per dolly). Might be this method: 4 dollies x 700 lbs = 2800 pounds. Please answer my question, so I don't break or damage my equipment. Thank you very much for your assistance.Moved a 100yr old pianocheaply Verymade. Cheap rivets holding wheels on . Every wheel popped off with only a couple hundred pounds. Even the pry bar looks like a 2 year old pit it together. Save your money. I can't believe how much they charge for this garbageThe lifting handle bent easily, the wheels are lightly riveted to the plate and came off easily, basically the whole unit (all the parts) just fell apart - definitely not capable of 3800 #, I would be surprised if it could help move anything over 300 #.Save your money.Really not good for any weight at all. They say they can handle the weight but even using 4 of these, it couldn't handle 400 pounds. DisappointingThey won’t work on carpet because it sinks into carpet and the lock switch is blocked so it can’t be moved. No way to get switch out of the way without locking it.
