stuartmMine was fine when I bought it but died after about 2 months. Great while it lasted, but the swivel mechanism seems to be a weak point. It started turning off and flickering while being rotated and finally gave up completely a few weeks back. I would avoid this in the future.
david_krafter a long battle klarus sent me a new one but it too has intermintant issues where it refuses to charge, i bought a basic 18650 charger and charge all the batteries that way now.
