The solution is always more. I ordered a Klarus RS10 for my Dad last week. He's been a lifelong 6V Dolphin user since the 70's.
He can't remember where the AAA Fenix I gave him a couple of years ago is. He pulled his Dolphin Mk6 out of the cupboard a couple of weekends ago for something and I was embarrassed for him when he turned it on.
I can't let him live like that, what sort of son am I?
