I lost my original inflator when I forgot to zip up my bike bag this past Spring and lost everything in it.
I don't miss that original inflator at all, it was very clumsy to use. You had to screw an adapter onto the valve stem and then screw the Co2 cartridge into the adapter. As you screwed it in the top pierced and the Co2 would start leaking around the adapter till you got it completely screwed in. And the cartridge was completely used up, whether you intended it to be or not.
With the new inflator I can control how much Co2 I shoot into the tire very easily. I was able to shoot a little into the tire before I changed the flat to see where the leak was, then after I put the new tube in I like to shoot a bit of Co2 in to partially inflate it and then let it back out. That may be overkill, but it's something my Dad always did when I was a kid to make sure the tube was straight inside the tire and wasn't pinched anywhere, and I still do it. Then I inflated the tire all the way up. All with one Co2 cartridge...
I'm liking the Air Chuck inflator a lot.....but, I'd still rather not have flats at all. /img/vbsmilies/smilies/wink.gif
That reminds me, I still haven't bought a new patch kit. /img/vbsmilies/smilies/redface.gif
