I have had more than one of these pumps. I actually go through more pumps than inner tubes! So, when I actually go to use the thing it may not have been used for a year. And yes, I ride everyday since I don't drive. By the time I go to use it the rubber o-ring has usually disintegrated. Today, the main shaft snapped off at the cheap plastic connector while I was trying to replace the o-ring. If you get one of these, don't leave it on your bike exposed to the elements. Maybe none of them can do this - but they should.
