Familiarity: I've put it through the wringer
I commute via train and longboard to/from work every day. Now that Winter Solstice is approaching, I commute in darkness both to and from work and I needed something to clip onto my backpack. This light helps keep me visible while kick-pushing my way down the road. Reflective tape on my helmet wasn't enough, but this light definitely helps keep me visible. I've gotten caught with it in the rain and it still works great.
My only complaint is the backpack clip. It's not very secure. I'm not sure if someone swiped it on the subway, or it just fell off, but either way, the clip is not sturdy enough to keep small bumps or sticky fingers from easily swiping it off my backpack. One day it was there, the next it was gone. So, I had to purchase another one.
