Joe B.wrote a review of Lezyne Mini Drive XL Front Light on December 8, 2012
Familiarity: I've used it several times
I bought a pair of these for offroad rides in the dark on my MTB. For the size and weight, they handily beat my 3 year old Cateye external battery lights. The mount is solid, the lights detatch easily, and can be charged via USB in pretty short order. I really like the hard aluminum case and overall construction. This isn't a cheapo light. I'll be waiting for a sale on other Lezyne lights for my other bikes.
