this is an email I sent to Princeton Tec:
Am avid biker/hiker/camper and have quite a few of your products, i.e., the Fuel ( three, two for gifts), a few "scouts", two "genesis handheld, even a few other items. Right now I'm packing for a weekend outing and dropped a "Fuel" headlamp. The battery door just broke off, upon further inspection, it should have broken off, by design. It is a horrible design; it is flimsy and discouraging that you
could market these items. I'm still on the original batteries provided so it's not like it's worn out. It might be manageable if this wasn't such a catrastrophic failure; the cover cannot be secured without that inferior hinge.
