Heavy Duty but needs options
Your review: The cart is well made and very heavy duty. This cart absolutely need to have locks on two casters and it is very unsafe with out them. The hard plastic wheels allow it to roll alomost indiscriminately loaded or unloaded. If your floor is just the slightest off by a quarter bubble this cart will roll on it's own. They need to have locks on two wheels not as an option which was not listed anyway but as standard equipment.
