Just chiming in to say I got my “rebate” from Sue, also. So they seem legit.
The Sofirn 2200 mAh battery tested at 2348 mAh on my Lii-500.
This light is exactly like the Boruit D10 in so many ways (UI, build, etc.) except with 2 no-name emitters.
But it does look a lot brighter and wider-beamed to me. The weight difference is negligible, but 1.87A to 2.49A max current will probably cause a noticeable drop in battery life for those who use the highest mode a lot.
