Quik Cart Pro Wheeled Rolling Crate

I bought this to replace a similar product purchased at Staples about a decade ago. That product lasted for years and really only failed because I dropped it down a (short) flight of stairs. The hinge on the bottom broke off so it was no longer stable. I'm not sure if they're the same brand. They look like it.It's hard to provide a good review for something I just received, but I'm going to try, because while the good part might end up not being true, the bad stuff is immediately obvious and might affect someone's choice to purchase this product. So let's start.Good things:- Very sturdy. Solid. Thick plastic. Looks like it will hold up for some serious use.- For people who need to carry *a lot* of stuff, it doesn't show this in any of the images, but a plastic milk crate will stack onto the top, allowing you to securely carry more stuff.Bad stuff:- The previous version I bought had sliders on the top edges of the sides. They slid from the back to over the joint midway along. If you slid them back, the unit could fold when the bottom was raised. If you slid them over the joint, the sides could not fold in. This made the unit a lot more secure, I think. Think about how a cardboard box forces the contents inside to conform to the limitations of its shape while a rectangular reusable shopping bag can be deformed by the contents.- The telescoping handle on the previous version was six to eight inches taller. This seriously affects how far in front of it I can be and the angle that my arm is at when pulling it. It's somewhat uncomfortable. I feel like it's going to ride up on my heels if I stop suddenly. I'm slightly above average height for a woman at 5'6" (168 cm), and if I wore heels I am not confident that I could pull this unit at all. I have no idea how a man would use it if he were of average height. Honestly, I'm kind of considering returning it if I can find a unit that's taller.
