Very poor wheel design. I have had several of these in multiple different places and every single one has broken where the wheels go into the holes on the bottom, and this is just after moving the cart a few times, on wood floors too. Even the tinier ones without wheels only are good for use for a few times, all 4 of the ones I've had, the drawers just have ended up bending over a small amount of time. And it's not like I have heavy stuff in them either, I keep craft stuff like markers,tape,etc. Which then makes it almost impossible to shut the drawers and use in general. Company definitely needs some improvements on the overall design of the products.
