Why do you give a 10-year warranty on your site and only 3 years on Amazon?
We would prefer to sell only on our site, but unfortunately, there is no getting around the market power of Amazon. That means that if you want to survive, you also have to sell on Amazon. We sell the same quality on Amazon as on our site. But we want to reward the customers who buy from us directly and not from Amazon. That's why we give these customers a 10-year warranty.
