They're very reliable, if you use them correctly. They are part of my belt and suspenders approach: I carry a CO2 cartridge and a mini pump, a spare tube and a patch kit. First flat gets a new tube and CO2. I can be back on the road in under five minutes. Second (and subsequent) flats get a patch and the pump. (It happens sometimes.)
