I placed the order for these replacement wheels late on a Friday. They arrived one week later, as shipping did not occur until sometime on Monday. They actually delivered to the wrong address, but that may have been my fault when filling out information. (I live on a circle and they delivered on the other side of the circle. Might have accidentally selected a very similar, but wrong, address.) I was able to track the package down minutes after notification of delivery. Wheels needed to be replaced due to an accident with the cart, not due to anything functionally wrong or worn out with the cart or the wheels. Customer service was very helpful. If you have to deal with MGI service, expect it to go well. This is the 3rd time I have had to call and have been very satisfied with the interaction each time. Well done MGI.
