I wouldn't expect anything from the company after 3 years of use. If you took it out on a single trip after you bought it and then discovered the problem, I would expect an exchange. But 3 years of hard use...no way.
Bingo...how some of these companies stay in business with sh t like this going on blows my mind.
They made an error initially and it should have been caught and handled, even a year in they probably would have helped...but three years in? LMFAO....
