Super disappointed 7 1

For me it's part of Zéfal mountain biking brand that has always been fairly average but still practical products. I always carry around a pump on me in my bag, and I think that historically it is a Zéfal. When I saw this one I found it very beautiful. But from the first use I was super disappointed:
-it is very heavy, its metal tip weighs a ton
-it is locked with a ring he must place well, irritating
-it is heavy, I have already said can be?
-and finally developed the worst: his system to lock on the valve is what is worse. It hurts the finger is not practical AT ALL, short, trash.
For the price it hurts. Zéfal, we do better !!

Oh yes good point: it is nice and you might like it ... as long as not used.
