Good locking chucks last a long time and unlocking them to insert and remove means the gaskets last along time. Granted, not all locking pumps are good. The Zephal bike mounted ones are as is the floor Specialized. They have worked so well for me I haven't ventured further. I did spend 15 years screwing and unscrewing a high quality Italian floor pump. Finally got tired of wasting so much time doing something that took less than a second on bike pumps. (And yes, I unscrewed a few valves with that pump.)

In my case, I'm extremely picky when it comes to features. It had been a long search for the ultimate mini for my needs before I came across this particular model. The pump in-question is the PERFECT for my me with the exception of that issue (carbon so it's very light, stores great in my jersey pocket, inflates very well for its size, has a nice hose that stores neatly inside of it, and has great aesthetics).
Silly first-world problems, I know. 😅
