Finalmouse is a controversial gaming mouse company. They build their business model around incredibly hyped, limited release products at high price points. They are as much a "gaming culture" company as they are a gaming mouse company.
Finalmouse has a closed Affiliate program that you can apply to via the link below. Only select creators will be accepted. They offer a massive 25% commissions on approved sales which is one of the highest commission rates for an affiliate program. The commission rate is fantastic but you have to offset this with the fact that sales of their products only occur on occasion and often sell out in under 1 minute.
