Cheap bit of rubber, didn't look like it should. The rubber folded over so never looked good with clear distance between the balls and shaft. On the 2nd time wearing it broke.
I am sorry that you had issues with your purchase, having looked in to the matter I note that you have not attempted to contact us, in future please let us know about any problems and we will always do our best to find a resolution. The item is quite thick and stretchy to allow for stretching, but is designed to be tight when fitted, so would not suit being over stretched.
