Handy when it works

It worked awesome the first couple times I used it. But then it started to leak and customer service is of no help.

Cool little device

In all fairness I just packed it and haven’t had the opportunity to try it out yet. I have full confidence in being happy with it Specialized makes great stuff and has never let me down yet.

Does the trick!

Easy to use and packs away nicely. I also find it more reliable than other brands. I have 2 of these to put in my SWAT box (one for each bike). They've been great since I've had them.

Would Recommend?: Yes!

I've stayed away from CO2

I've stayed away from CO2 in general, preferring a patch kit and pump. After using a friend's cpro2 trigger for a slow leak, never going back. I was able to reinflate several times as I limped home.
