Hi Mike, thanks for sharing your thoughts! We're delighted to hear you found value in your purchase. It's a bummer the extra shelves and cabinet were out of stock. We recommend reaching out to Home Depot directly for restocking updates! Regarding the locking casters, they were designed not to swivel as an anti-tip feature to prevent the cabinet from tipping. We appreciate your understanding and thank you for choosing NewAge Products! If you have any further questions or need assistance, feel free to reach out.
