So, I went to REI to buy another blackburn mars 3.0 today. I have one, and the bracket snapped off when I was moving it around on the seat post. REI only had one, the display model. I didn't test it out. When I got home and turned it on, it blinks at double or three times the rate of my old one.
I also seem to be going through AAA batteries with the old one at a pretty good clip.
So, what is the normative rate? ( I imagine it's the slower one) Should I bother returning one? Should I attempt to fix it? What's the cause of slow/fast blinking?
