Buy in France, but the gauge doesn’t work, the needle is outside the dial area. My Specialized store can’t change it, because not yet sold in France 😱.

J'ai apprécié de gonfler rapidement avec la cartouche CO2. Malheureusement le trou dans la chambre a air etait trop gros. Attention de ne pas se geler les mains suite a la détente du gaz!

Muy sencillo de utilizar y mas eficiente con el regulador

Used on a ride tonight to fix a flat, can't even explain how much time this saved compared to trying to hand pump it.

Great product allows one to modulate pressure

It threaded onto the presta valve and CO2 came out when I pressed the button. The tire inflated! But then the gauge broke and read 50psi all the time. So I asked for a replacement, and after one use, the gauge on the second one broke and read 50psi without anything attached. So I asked for a refund. This would be an amazing tool if it held up. It would also be that much more amazing if it had a clamp instead of threading. To be able to add pressure really quickly -- like in a matter of seconds -- when switching from dirt to pavement would be awesome!

I purchased this product on a bike tour. I could not figure out how to use it. I tried to press down like a floor pump. Only when I took it to a bike shop did I realize you carefully thread the nozzle onto the threaded valve stem! These work fantastic and are great for touring because they take up less space than a pump. I flat with Tannus armor is a once in a blue moon event but when you get a flat out in the middle of nowhere, these pups are a godsend. In response to Neil M.'s negative comment, they must have stripped the threads on the nozzle. It was not the product's fault it was used by Neil M.

Genial

Funktioniert gut

Not very good sorry to say but got stuck on my wheel valve & had to rip it off as could not get it back off !

Works great. The push-button trigger works better than the between the fingers conventional design.

This is a great tool … I alway worry with CO2 if I have enough or too much Air pressure in my tubeless tires and this tool is a life saver out on the road...

Failed me on a ride. CO2 wouldn't come out no matter how hard I pressed the trigger or adjusted the seals. Thankfully I hadn't taken my cheap old one out of my bag and had more co2. It allows air to be blown thru by mouth as designed so there is no blockage. When I got home I experimented using different gram weights. None worked. I have a Specialized bike, helmet, etc but would recommend to everyone to never buy the CPRO2 gauge trigger

Muito leve e util!

Simply stopped being able to expel co2, on or off a tire, the second time I used it. Left me stranded up a trail. Do not trust your bike or safety to this thing.

I bought this last season, and have never used it. I went to use it for the first time yesterday, and no CO2 came out the valve. I thought the cartridge must have been dead, so I detached it and it sounded like a gun going off. Total junk. Very disappointing.

A friend suggested I should invest in the CR Trigger. I couldn't be happier with the way it works. Get product!! I highly suggest.

I've only used it once but found it extremely easy to use. It screws on easily to my presta valve - air does not leak after it's screwed on. The button allows you to easily control the flow of air and the gauge is extremely helpful. Great little tool to keep in a bag.

I have used mine a few times now and have had no issues. It cinches down nicely on the presta stem and I have been able to gently release the C02 with the trigger..
