I originally received this product in exchange for my unbiased and honest review. Thank you DelRey! In my job (field worker, electrician) I sometimes have to drill a few holes. I have some center punches and a small ball-peen hammer. I hadn't heard of Dead Blow until I hit this hammer (hey, I'm an electrician). So far this pair is working great. The striking tip does its job, and the unerring strike of the hammer happily explained this riddle of rebound to me. Of course I'm not sure how long the pair will last, especially the spearhead - I'm hard on tools. So maybe more later as time goes by. But right now I'm the envy of all my electronic friends. (And you know what they can be.)
