Can you write more about how you provide a warranty? Is it simply guessing x% of the products will fail within the warranty period and set aside some money to cover those failures. Or is it more complicated?
Hmmm, it's actually much more simple than that. We want to provide a good product that makes people's lives better. The warranty is a forcing function.
In my opinion, if we can't make money while ensuring people's CoBattery cases works, we shouldn't be in business.
