Princeton Tec headlamps
 

I bought a Princeton Tec headlamp probably three years ago. The plastic swivel broke, that allows you to point the headlamp. My wife bought me a new headlamp for my birthday, but it looked inferior, so I looked up what kind of warranties PTs have, and it turns out they are good. I called them up, they said to send me the old one and they would fix it. Today I got a new one in the mail (I guess fixing it wasn't worth it).

I endorse Princeton Tec products and service.

and they threw in a new set of batteries!
