12" Mini Pro Break-Away Rim
Product Review (submitted on March 23, 2014):
Researched and could not find anything that compares to this rim. It is a bit pricey, but it will hold up to serious abuse. My boys (6 to 10 yrs old) can literally hang on this rim. They love it because they can dunk as hard as they want and it makes them feel like they are big time!
Works perfect with a standard mini ball. Just make sure you securely mount it and you will have this rim around for a long time.
