A+ customer service for the block: update
I called Field Logic and told them that I was shooting through my block target after about 600 shots.. They told me to go out and lift the plastic wrapping up and see how loose the bands were. I did and they were tight, but not tight enough. He told me to flip it upside down, so I did. I then checked the bands. They were tight. He asked me for my name and address. He told me to expect a new target at my door on Thursday! That is some of the best customer service I have ever had!
