I am really getting overly sensitive about mini pumps. Over the last 10 years I have had 3 fail me on the trail. One just plain broke, one the chuck failed, and the last one just plain wouldnt pump air.
I got a give certificate to a bike shop for Christmas. I decided to get another mini so I dont have to switch it between by bent, and my trike. Yes I still carry one, but only as a backup. I use a CO2 inflater now. Both the bike and trike have presta valves, and on one occasion I broke off the stem trying to use the mini. So I wanted to get a mini with a hose so not to break off stems.
At the LBS I told the dealer what I wanted, and he showed me a mini with a section of hose, a built in gage, and a swithable chuck. Fantastic I thot, everything I wanted and more. Yup all those features, and when I got it home the damned thing wouldnt pump air. The dealer is ordering in another one for me, since I really do like the design. Lesson learned, try before you buy.
