I previously posted a thread concerning the empty promises I received from Bumper Boy, but I am now posting to let everyone know that they made the situation right! I finally received my repaired units, one which was replaced with a new one much to my liking and my surprise! As my luck would have it the brand new one had a faulty upgraded receiver and would not work.. I was not happy! However they tried to help fix it over the phone and after having no luck at all, they express shipped me a brand new receiver. Upon replacement, the two twelve shooters are better than ever with no misfires and awesome new electronics! I was quick to post when I was dissapointed in their service which could have been more upfront in the beginning, but I commend the folks at bumper boy for taking action and putting two fine launchers back in operation at my training kennel! Guess I am not done with bumper boy after all!
