Daughter pitches fastpitch softball and we had one of the rubbers with the 3 spikes that screw into the bottom out in the yard. While it has held up well, it does get kind of lumpy where the spikes are and we have to move it around every few days. This rubber is much better as it's the regulation size and sits nice and flat. Well built and I expect a few years from this no problem.
