I've had two "Blocks". I primarily use them to shoot broadheds, though. I have been disappointed that the broadhead blades tend to slice small slivers of the foam layers and they come out with your arrows. I have movable spots that I place in different areas but it ends up that if I shoot 10 or 15 arrows at the same spot small pieces of the foam layers slice out leaving a weak spot. The problems is that I haven't found a better alternative for a broadhead targets. I can get about 1-1/2 seasons out of my block (the smaller size one) and that's about it.
