HOTRONIC TWO YEAR WARRANTY Hotronic warrantys their product for 2 years from date of purchase!
Our comments; For the small difference in price between the S3 Series and the S4 Series, we feel the S4 is the better value because you can use a higher heat setting for all day heat. And Hotronic is the only company with a two year warranty.
With so many options, I wasnt sure which to get so I called. I spoke to Rich. He knows boot heaters!! He asked me a few questions on how I was going to use them and made 2 recommendations. I selected the Hotronic because they had a 2 year warranty. You never know if youll need it. I also got free shipping and didnt have to pay sales tax. Ill be back for more stuff from Alpine Accessories.
