We had to replace a system that the bolts were coming loose from the concrete and decided since our 6'1" basketball loving boy plays travel and school ball, that a stronger and sturdier hoop system was needed. This system has been fantastic for us. It was easy to install and since the cap is metal and part of the pole, we don't have to worry about rain running down into the concrete support and eroding it away. The mechanism to adjust the rim height is super easy to use and since we get lots of straight line winds - a must to be able to lower. Overall you can't go wrong with this system.
