HD Switch is not just a Switch company. We are a Design Engineering Firm. We Re-Design and Improve almost everything we sell. Stronger, Better, Faster, More, Cheaper…. In this case we Switched the shape of this product to add strength. Where the original design was weak, we changed the shape to add strength. Then, we Switched to a tear resistant high tensile strength rubber, making it nearly impossible to tear. We are so confident in our Design we offer a lifetime “no questions asked” Warranty.
