There are a few things that I think you may be misunderstood about. First, I don't need anyone to R&D or test my product. I have thoroughly done that and proved that it does in fact work. I have made videos (FB page) of side by side comparisons with and without my product shooting sheets of various thicknesses of plywood using various bows and arrows of different makes, models and weights. I have also used it in the field with great success. Second I do understand the benefits and tax deductions available, but again I don't need your help with this. Third, I never made any claims to be "the best of the best". I really don't know of any other product like mine on the market to compare it to. Patent search did not discover anything similar enough to be considered an issue in this area. Fourth, every hunter who spends any amount of time in the field knows that things happen, and not every shot is perfect as planned. You can shoot daily, as I try to for months before season, and still have some unforeseen issue when the shot is made. Nobody will hit a vital pass through every time, all the time. My product is designed to help with hard hits on bone etc, and have little to no effect if hitting soft tissue. You need to understand and use something to speak intelligently about it. Anybody can make comments and speak negatively about anything, but I want to hear facts and numbers. The Slidehammer TM is based on basic physics. Force= Mass X Acceleration. When you rearend the car ahead of you and are not wearing your seatbelt, you are likely to hit the steering wheel or put your face through the windshield right? If you had a truck with 2000 pound weight that was loose in the back and hit a tree, it would come forward and smash the cab would it not? Wouldn't the weight make the truck hit harder? Same thing on a smaller, faster scale. I Figured I would need to give a simple minded nay sayer like yourself a more basic explanation on how it works since you have not seen it or used it. Great story about your buck, but It has no bearing here as it sounds like you did not hit much, if any, bone which was the point I was making about my deer. The Slidehammer is designed to insure penetration on hard impact such as bone. I have proof to support my claims about the Slidehammer TM (videos, dead Bucks with holes through their shoulders!) and I am okay with people being skeptical but not okay with someone making conclusions to others without having actually tried it or even seen it in person. Anybody can talk, blah blah blah, I heard, I think, he said, she said, I didn't do my research but...., I never saw it but, I never used it but.... How about backing up your talk with "I bought it and tried it and..." How about, "I witnessed my friend (Ted Nugent or whoever) shoot it and ..." instead of, "I never held one", "I never bought one", "I don't know anything about it really but..."
