I was able to use my crankbothers gem mini pump and topeak floor pump without modifications. There was no leaks and was able to pump my tires to 70 psi wihtout any issues.
Normally my pumps would leak a little bit when connected to presta especially the mini pump. It made pumping to the correct pressure longer and very annoying. But with clik valve it was quick and easy.
I changed the crankbothers to the schrader side, plugged the adapter in and lock it. It sat almost flush with the pump head and there was no leaks.
For the topeak, I didn't have to change anything. I just plugged the adapter into the head and lock it in place. It stuck out noticeably but it did not leak when pumping.
Easy to use, pull off/ push on. Brilliant design makes checking tire pressure fast and simple, even with full finger gloves. Bright colors aides location
Half a dozen rides so far and they are solid, which is surprising since they're only pushed on. Makes it easy to inflate
Vert easy to use and functionne as advertise
Very satisfied
