Each of the four dollies comes in its own flat box with its own hardware included in that box. You’ll need a wrench. I did not find one in the package. Overall I was surprised that I had to put the wheels on the dolly. I’m terrible at assembly and it took me 15 minutes to put the wheels onto one dolly. But I do think this is a nice product that will work well. I’m giving four stars instead of five because I found no wrench or instructions in the packaging.

These are very heavy duty! You have to attach the wheels but it was easy to do and didn’t take long. They are meant to place under barrels but I anticipate many uses to save my back as well as my husbands! This is a great quality product!

These work as intended and are sturdy enough to hold the advertised weight. The wheels roll freely and make moving heavy barrels easy. I gave it four out of five stars as assembly was more difficult than necessary as the nuts and bolts for wheel assembly go into tiny holes and facing up makes it less than ideal unless the barrel you have has a lip on the underside. If not the bolt will have full weight of it poking into the bottom side of whatever you have sitting on it. Seems to be functional and worth the money for sure.

Just what I need. There are 4 very heavy and sturdy dollys. I do recommend purchasing these they are worth trying you wont regret it. I have moved thing around the house and they maneuver really easily.

Every year I grow vegetables on my deck. I can't grow them in the ground because of the critters than wander thru my yard. Every year I buy plant caddies so I can move them around following the sun. Every one of them says they'll hold a lot of weight and their wheels will continue to roll. Every year I'm forced to buy new ones because, by the end of summer, they're toast. So this year I got these - heavy, steel, beefy wheels bolted on with 4 bolts, made to carry 55 gal drums. I will be that by the end of this summer these will STILL be going strong! I love them.
