Pros: Brightness, None
Battery controller quit after 7 recharges, bad customer service
Pro: reasonably bright when it works. Cons: doesn't work, got quite hot when it did work, terrible customer service from both Knife Center and Fenix. I completely regret buying this light. My 27 year old Petzl Zooms are back in my truck and my gear bag because, while a bit heavy, they work. Knife Center said that they don't support fenix products they sell and fenix has had the case for over 3 weeks and won't respond to emails.
