Volt resistance leather 7v heated work gloves - Volt Resistance Leather 7V Heated Work Gloves - Mens

I have had Volt Resistance Leather 7v Heated Work Gloves for a little over two months now. I a very disappointed in this product. I work in a cold storage warehouse and I can barely feel the he within the gloves while in the warehouse. I have the gloves at the highest level of heat and my thumbs are the first to get frost bite and after that I start to feel frost bite on my finger tips. And now there is a issue with the left glove, it's not staying on anymore and I have used two fully charged batteries and all they do is flash all four blue lights and then go out so it must be a wiring issue with the left glove now. I purchased these gloves at the end of April and it's the beginning of July, I should not be having these issues right now with gloves that I paid over a hundred dollars for. Please send me a better model or give me my money back.
