I moved out of Stripe because stripe charges $15 for charge backs for my product worth $10. The dispute resolution mechanism sucks and it almost all the time favors the customer and stripe is US only. My product is worldwide.
That being said, $15 is a low chargeback fee (damn close to cost the issuing bank & platform charge), generally you'll see a $25 to $30 chargeback fee with a $20 to $75 retrieval fee.
