Climbed Mt Evans today. The descent proved bumpy enough to cause a pinch flat. Luckily I swapped out my old leaky inflator for this JACO one. I really needed it to work because I was out of service and still miles away from the non-toll road... AND IT WORKED. The product performed as promised and got me out of the jam. I ended up hitting 50mph+ on my spare tube -- wouldn't have been possible if this inflator leaked at all. It safely pressurized the tire. This inflator is easy to use, robust, and dependable. 100٪ would recommend.

This is simple and effective and works exactly how it is described and expected to function. This takes threaded CO2 cartridges so make sure to note that when getting refills. No issues so far.

This discharges as soon as you put a cartriidge on it. Worthless, in fact I started carrying my bike pump again because I can't depend on these!

I’m a long-time use of the Lezyne flex hose inflator which is a very different style. I’m always on the lookout for a better option so I often try different ones. This one by Jaco is not going to replace my Lezyne. It’s fine if you’re looking for a small chuck-style inflator that has a simple, straightforward operation but it just doesn’t work as good as my Lezyne or even other chuck-style inflators that I’ve used like the one by CXWXC. One issue is that you have to make sure the cartridge is attached just so. If it’s too tight CO2 won’t flow. If it’s too loose CO2 leaks out. The mechanism works by simply pushing down on the chuck and that’s where the appeal might be. It sounds easy but the flow is erratic and inconsistent. It also doesn’t seem to empty the cartridge completely. An inflator that has a mechanism that you turn makes starting and stopping smoother.
