I've cycled for 20 years, half of that added up was riding to work and rode from Utah to Panama, so a lot. I still have not figured out quick links. I've had bike mechanics and people on bike rides show me how to connect them by pressing them together on the sides and tugging but I can't do it. It is some kind of ability you're born with or you're not. I am not. These have already saved me enough frustration in just two bike chains to justify the cost. I'd recommend these to anyone who owns a bike.
