Some of the products that we sell, like the Enersound T-500 FM transmitter and the R-120 multichannel receivers feature product lifetime warranty, which means that any malfunction will be covered by the warranty and the buyer will receive a new unit or free repairs of their existing one, depending on the situation. And this will extend during the lifetime of the product. Electronic devices don’t last forever, and it is expected of them to die out after a certain number of years, but this period should last at least 10-12 years depending on the product. When ordering a product with lifetime warranty you can have peace of mind you won’t have to worry about replacing it after a couple of years.
