Review on Stainless Steel Locking Fasteners for Marine Pins - Safety Coupler by Chef Buntiloy

I bought these after seeing the Tucktek kayak upgrade recommendation. I was a little unsure at first but after spending some time figuring out how to attach these pins to my existing cotter pin setup I was very happy. They are very secure and I'm not worried about my kayak unlocking while swimming. Used a few times and they are holding up great will buy more if needed.
