I'm giving this a 2 star review based on how sharp the edges on the vents were.
I do alot of saltwater inlet and surf fishing requiring long powerful casts. The vents are at such an angle that they dig in and cut the inside of my thumb, then saltwater gets in the cuts and it's just no fun. Good seat, locks positively. DO NOT use if you plan on doing alot of casting or putting power into your cast.
Functionality: 9/10
