The cart assembles quickly, looks good and, with one fatal exception, is sturdy. The fatal flaw are the wheels and the pieces of cheap plastic into which the wheel shaft is inserted. The wheel shaft receptacle is made of flimsy plastic and the wheel shafts do not "click" into place like they do on other products (like office chairs) that use metal receptacles. I suppose the weight of the cart is supposed to keep the wheels in place. Anyway, the cart moves great on hard floors, but the VERY FIRST TIME I moved the cart from a hard floor to carpet, the cheap plastic that the wheels are made of just broke into pieces, sending my microwave flying off the cart! The wheels are completely ruined and the cart is now just a shelf. Lukily, my microwave landed on carpet and survived intact. Of course, the boxes got picked up with today's trash, so we'll see how responsibly this is handled by Wayfair and the manufacturer and I will add to this post (if it is allowed).
