Works-like they should

• Familiarity: I've used it several times

Hard to get excited about CO2 cartridges, but these work and are fairly priced. Here's a hint: I found that when you flat in 90 degree heat and are dripping with sweat, anything you can do to help the situation is valuable. These cartridges(all brands) are slippery. I take a short length of old tube and slide over the cartridge (23 is tight so you may have to lube cylinder with a little liquid dish detergent). Now you'll have a better grip to tighten the cartridge into your inflator head AND it insulates you from the cold as cartridge discharges.
