We stand behind our product! If your Gear Saver fails due to manufacturer defect we want to know and to replace it free of charge. Contact us to send yours in and we’ll ship you a new one. That being said, if yours was in the vehicle while you were baking cookies on the dash in Arizona, or your carbonated beverages were exploding in your car because of frigid temperatures in the Northern latitudes then realize, that was beyond the scope of the product. We’ve used the best glass reinforced nylon material and spring type steel available, but normal wear and tear will eventually, like anything, reduce the effectiveness over time.
