"I bought twin hoops 30‘ and ordered this add-on so as to extend the hoops to 33‘ every now and then.
My experience with the extensions is this: when the hoop was 33‘ for a while and I remove the extensions, everything is fine. But when the hoop was 30‘ for awhile and then I put in the extensions, the shape is not really round, i.e. flat on one side. After a while (maybe 1 day, depending on how warm it is), the hoop adapts to a perfect circle in 33‘.
30‘ is the perfect size for me for doubles and the extensions were just for testing or experimenting with another size. So, I am very satisfied with the product.
