CXWXC 16g / 25g Threaded CO2 Cartridges or CO2 Inflator for Bike Tires - Cartridge for CO2 Inflator with Threaded Connection, CO2 Pump for Road and Mountain Bikes

I hope I'll vever have to use it.

They are what they are. Haven’t used them yet but they be in the saddle bag until required

Ok

Easy to use as any other cartridge. Portable and a solid charge. I used it for an unconventional idea, and uploaded the video. The design worked better than I hoped. Check it out, and you won't be disappointed with the cartridges.

I used these for testing my Onyx M-16 life vest. I wanted to keep the original equipment manufacturer OEM cylinder for actual emergency use, but these cylinders are PERFECT for testing my equipment to make sure that my life vest is free from holes and that the actuator works. Worth every penny! I swap one of these cylinders in for testing, go out in the lake and tried this so that I knew what to expect when I pull the cord in case of emergency. Once back on land, I dried out my life vest, repacked it and installed the OEM cartridge (and re-arming pin). For this purpose (testing) these cylinders were completely indistinguishable from OEM at a fraction of the price of OEM.

These o2 cartridges were used for our life vest. Worked well.
