I've had the Magicshine for a little over 5 months now. I run it during both the morning and evening commutes 5 days a week, regardless of whether or not it is dark. If it is day light out, I run it in high speed flash mode to avoid left/right crosses by making damned sure that drivers know I'm there. My commute is 9 miles each way. I charge it every night.
It's doing well so far. For the $85 I paid, I cannot complain one bit. I don't know of any other proper bike light this bright for less than $400. Those LED flash lights aren't proper bike lights. This is by far the most bang for the buck in bike lights that I've seen.
I haven't decided what to do with my Light & Motion ARC. The battery died and a new battery alone is $200.
The Magicshine is bright enough that you can ride at a decent speed, even in what is otherwise total darkness. That is a must for me.
