I was very happy with this little pump. I used it successfully once. I previously had the Innovations Ultraflate Plus CO2 by Genuine and this thing caused the co2 to blow up in my face (slight exaggeration)...on threading the Ultrafalte I somehow cross threaded and when it punctured the cartridge all the air went flying out as I had it close to my face to look to see if I was threading correctly. Thus, that day I was stuck in the middle of nowhere and a long walk into the dark evening. ANyway, this little Air Kiss seemed really nice (much simpler to thread)....Then, last weekend I was again way far away from any stores, out of phone coverage, and got a flat. I pulled out the air kiss and new cartridge expecting I'd be up and riding in a moment to find out that the little puncture insert (little metal washer looking thing) had fallen out of the Air Kiss and therefore I could not puncture the co2 cartridge and again was stuck.
Now, I not only carry a great little hand pump, but I upgraded my co2 to the Portland Design Works Shiny Object CO2 Inflator....this one is a much better desing.Get more detail about Planet Bike Air Kiss CO2 Bike Tire Inflator.
