It takes some getting used to, the tri wheel doesn't require the exertion to go up stairs as a cart with a single wheel and the temptation is there to tug much harder than is required.
Works great for one person move down 40 steps. I stacked and strapped 2 - 4 gallon containers and many loads later I'm almost done. 100lbs not problem but I wouldn't do anything heavier.
The wheel is held in place by a pin you have to bend and that was hard causing a few finger pinches
the wheels are super stiff to start took a couple tries to loosen them .. Afterwards it did alright and was able use it over bumpy terrain and move a few things with it no problem.
