Wonderful helper. I have trouble walking and carrying things so when I am trying to clean out closets or drawers, this is a very handy little cart. I add a trash bag on the side and secure it with a clip. Then I use the top shelf to sort and use the other 2 shelves for "keep" items and "donate" items and then I have the trash bag right there for items that need to go.
There is no assembly really, just open the Velcro strap, unfold the cart and you're ready to go. Just press down on the top shelf to make sure it locks open. I can leave items on the cart if I get too tired to finish and roll it to an out-of-the way place until next time. I like that the shelves have a lip and are not flat so that items don't fall off. It rolls very smoothly and is easy to steer and maneuver regardless of how loaded it is; it really kind of glides it is so smooth. And when you are finished with it, it folds very easily and does not take up much space. Just watch your fingers when folding it. You could store it behind a door. I have rolled it down one step and it should be okay on 2, maybe 3 steps if you are careful but I haven't tried that.
I have 2 of them and may order another because I am sorting and trying to clear out as much as I can while I am able. I think this would be great in a workshop or craft room. Very satisfied with my little buddies!
