I posted some pics of the M2 about three months ago (page 5). I finally received my Legion II this past Wednesday, and after using the L2 for a few nights, I'm very impressed with the finish, balance, UI, and output. Though the wait was arduous and sometimes frustrating, I think Neo has finally found the right mix of quality and design to make a near perfect product.
My light arrived with zero flaws. The only thing missing was a little lube on the threads, but that was easy to take care of myself. The finish is perfect and the HA color matches throughout. I popped three Tenergy cells in, turned the ring, and enjoyed the rediculously bright, even beam. The UI is very easy and intuative - it's quite simple to customize the setting as well.
Compared to my Eagletac M2 (3xQ3), the MC-E in the L2 produces a more balanced diffused beam with the OP reflector but still has the ability to throw like the M2. The donut produced by the MC-E is minimal (if even noticable at all). My initial thoughts are that I like the L2 much better: it's more balanced, feels much more solid in my hand, the UI and selector ring are superior, and frankly it just looks better. The only thing I prefer with the M2 is the fact that I chose the Q3 warm tint option - really nice outside in the woods.
