These rolling carts are the best.  I have them all over the house.  This is the first double cart I've used and it is wonderful, too.  I don't roll them around much as most of mine are on carpet but the double in in the garage on concrete and it works very well.  The drawers are a great size and the double cart had two different sized drawers. For the price, I don't mind that the drawers occasionally drop out of the track; they don't go far and as I've used them, I've learned to manage that small annoyance.  They are simple to put together and have always come with the correct number of parts and pieces.  They are light weight and yet pretty sturdy when assembled. Love 'em!
