i will not be returning this product, it worked fabulously, i hauled my heaviest air conditioner down first. moved it down 2 flights of stairs to the basement from a second story in a duplex. it worked great, i even pulled upwards on it to test going up and i could move it upwards easily, so i will be able to bring them back up as easily as well. i did use a strap i have and i would recommend buying one (ex: AUDEW Ratchet Tie Down Straps 4 Pack Ratchet Straps 20 FT-1500Lb Break Strength Cargo Straps Heavy Duty Lashing Straps) to cinch it securely to the cart so there is no chance it would ever fall off, and using the enclosed bungee to hold up the leg when moving item. overall it worked very well and i wont be worried anymore about getting them up and down the stairs and needing help from undependable people. i can do it myself.
