This is the best stair climber cart I have. It is also the least expensive. The wheels are big enough to get up and down stairs without gouging-out/tearing wooden stairs as the other one I have does. It is very sturdy. I am going to get another one, if that tells you anything about the value of the cart. Don't waste your money on the cheaply made, wobbly ones. I highly recommend it. It has a 330 pound weight capacity.
I've used this item to remove many planters from my basement this spring and it worked like a charm. I like the large platform to hold the items moved. I tried to take some bulky items (bags of softener salt) down the stairs but it was not the as labor saving as taking solid items up the stairs. In a few weeks I will start to bring many of my plants inside to winter over and will know then how easy it will be.
The Cart is as advertised, but assembly is required, and no directions were included, and the online version is inaccurate: wheels are held by pins, not bolts. Not hard to figure out, tho.

It does what it says.I think it's kind of heavy for a woman to pull up the stairs and I'm a strong woman you put a 50 lb bag of salt on top of it it really is heavy but I think I'll keep it and use it for different things in my garage moving things around and for the odd step project but again I think it's quite heavy structurally and that makes it quite heavy to maneuver with a heavy object on top of it a man probably could handle it very easily.
Used this for moving a fridge into a house. I would say that is the maximum weight as the wheels were pretty compressed but without it would have been a nightmare. Just having the weight transferred between steps was a great help.
