text: Very bright and has a ton of modes, but it didn't last long. I bought in January of 2017 and I use it about 5x a week for several hours a day at work, I even use Nitecore batteries and a Nitecore charger. The power button is not user friendly, and now the light only works on 2 brightness levels, no more turbo mode! I've tried fully charged batteries and even some new cr123 Batts, but nothing is helping. Now it won't even turn on until I've held the button down or clicked it 30+ times. I'm pretty sure it bit the dust.
