How do you lose "keychain" lights? Do you lose your keychain as well? My original Tube is a good three years old and works as well today as when I first got it. Rarely used so maybe that's why. I almost bought the Tip SE last month to add to a couple keychains (and replace my Tube) but I ended up with two of the new Tubes (V2) instead. I carry a keychain flashlight but I really have little need for them. I keep a couple more powerful lights in my vehicles.
