Mine's still working fine, too. As an aside, I just picked up one of the accessory kits for the 24/7 - it adds a headstrap that lets you wear it as a headlamp, and angle it up or down, a magnetic base that also lets you angle it, and four wall mounts and anchor screws to secure them.
I think that the headstrap makes this neat gadget light a much more practical light - and the magnetic base is also a good addition.
