This is nice, versatile way to save space and organize your smaller dumbbells and miscellaneous equipment. It includes a few different hooks that attach to the sides of the cart (a row of hooks, workout ball holder, ab roller holder). There are a few different places you can attach them, and they're optional, so you don't even have to use them if you don't want to. You also have the option to use wheels or flat feet for the bottom of the cart.It is nice that the width of the dumbell racks are adjustable. They're not, however, really heavy duty. I believe the weight limit is 120 lbs per rack, and that seems about right. I wouldn't trust it to hold more weight than that.I'd definitely recommend this rack. It's all good size and it's several options make it a versatile space saver.
