I have the taller one with a single row of drawers. It is definitely not good for anything heavy because the drawers will come off the tracks, but I store adhesives and refills, extra trimmer blades, plastic sleeves and bags, my staple gun, small stuff like that, and it's handy. I keep it next to my worktable and have my heat gun and iron on top.
I'm thinking of getting the one you linked to as well to slide under my worktable for storing other stuff. It's on Amazon in several sizes

and as you can see the reviews are mixed. Some love it, some complain about the drawers. Seems like most of the complaints are from people who wanted to store heavier things or teachers who wanted to use it in a classroom. It's not really meant for that kind of heavy use IMHO. And be aware that the drawer measurement is for the top of the drawer. It narrows down at the bottom about 1/2 inch.
Postscript - just ordered it from Amazon. Price not much different and I'll get it faster I think. Hope it fits where I want it to.
