Satisfecho

Once pressed, the inflator doesn't stop pushing air. After a dozen uses, the lever that seemed to control the airflow doesn't. Battle to get it off before it blows the tire, which seems like it will once you've locked it to the valve

Outstanding and light!

Having bad luck with these things. This one was to top off a hand pump and ended up letting all the air out when it would only partially puncture the cartridge. Tried a 2nd cartridge and same thing happened. Trashed it at next stop.

Worked a couple of times ok then just seemed to only partly punctured cylinder and let air most of air escape before even applying to tire inflation nipple. Pretty poor quality materials used in manufacturing.
