Finalmouse makes mice for gamers. Although they are designed to be used by professionals, nothing prevents an ordinary so-called "casual gamer" from exploiting all the benefits of their products. After all, everyone wants a light gaming mouse with incredible precision and high quality.
Finalmouse has an affiliate program where they will offer a unique discount code specific to you. If an order uses that code, you will be credited for that order and received a 25% commission from the sale.
This is a great program if you already use Finalmouse products and are an advocate.
