Assembly of this cart is easy and straightforward, except for one thing: you must match the left and right legs to their proper positions. Everything's identified with molded-in \"L\" and \"R\" markings for that purpose, so it's not the hardest thing in the world. In any case, if you're feeling the need to drill holes, you're probably doing it wrong! After assembly, the cart is incredibly strong, solid, and easy to roll around. Nice touches: the bearings of the two caster wheels are well greased, there's an extra piece of each type of fastener, and there's a cup holder. VERY happy!
