My solo died on me last week. One year and 10 days old.
Battery is toast. L&M sells the batteries for $80. Ridiculous!!
My LBS is trying to get it warranted... We'll see, I don't have high hopes as they only offer a 90-day batt warranty.
Despite the battery issue, it was a good light when it was working. Like I said above, it doesn't light up the night like day (or like some of the HIDs I see)... But it's good enough.
