I use these bases a couple days every week coaching a little league team and they work great.  Good price - much better for the money than the set of really thin ones I got before.  Only issue is that I do have a small hole in the home plate due to kids pounding the bat at the base as part of their 'step-up-to-the-plate' ritual.  So ... don't let them do that.  But the quality has been very good.
