i would sooner contact a Rep. but saw this review and decided to write on here!!!! My son and i have both purchased this item and it is a great product . work well but the gel pack on mine last about 4 heatings and my son's did last a couple of weeks. We checked the microwave wattage and that wasn't the problem. I have since got rid of mine because of the gel leaking but i still have my son's here out of reach of anyone, hope i can get some feedback on this.These items were only used by adults and never miss treated.
