First unit delivered had some welding issues to one of the shelves. Wayfair immediately arranged for a second unit to be delivered. Due to the current issues with all deliveries in general, it took a little longer than usual. This second unit was in excellent condition and well built. This shelf is perfect for I needed and Wayfair service was excellent. I would have given 5 stars if the first unit delivered was free of defects. 5 stars for the service, regardless.
