I also use the 4x4 block, however, I store in indoors, and I only use it for broadheads, and I don't shoot it a lot, when compared to how much I shoot field points into my 3-d's. SO, this target may last me a decade at the rate I am shooting it, which I guess isn't much of a good test to how it holds up. For what it's worth. The arrows do pull out easily, not one finger as was advertised, but easier than any of my 3d's, that's for sure.
