I bought mine a few weeks ago, and couldn't be more impressed with it. It outputs 3200 lumens in a wide searchlight type flood beam with a perfect super bright hotspot, and is the brightest light I have ever held in my hand! I also love its 7 LED flashlight built into the handle, which comes in handy all the time.
Ive only had it for a week but thus far my M2 paired with a Solarforce R2 drop in has really surpassed my expectations. I was wanting a step up from my 6P and I think think this setup really delivers.
