I bought this based on my love of the BELL brand for over 40 years. Now I'm paying the price for being the first to follow: * No removable battery * Weak, ridiculous pocket clip - mine engaged in less than 2 tries * Virtually no "locator" for the air valve - it's finished FLUSH the gauge, so you need to keep the gauge right in the middle of the filler neck * No nipple to easily vent excess air. In general it feels, looks and performs like something out of a 99 cent store. I won't even returnβ¦
