Oh, Dad's got plenty of flashlights already - I guess I'm a good son when it comes to supplying him with useful gadgets. He's just a bit lazy when it comes to replacing spent batteries so he ends up borrowing my stuff now and then.
BTW, when I bought that Fenix light it came with an extra note saying it shouldn't be kept on the turbo setting for more than a few minutes. I'm pretty sure they wouldn't replace my light if I sent it back but then again, I haven't even tried and I doubt I will, too much fuss.
