For the price, these bases are a steal(no pun intended). They're high quality, and they tend to stay more or less in place on a dirt infield. They'll move around a little here and there, but no less than can be expected from bases that aren't tied/screwed down. I just wish it came with the back part of home base for softball, but I know that's not what it's supposed to be used for so no points taken off or anything. Great quality rubber, the bases have held up great so far.
