Received mine as well. First impression quite positive. Yes, it is not for modding, no Anduril, it could be lighter or have better head strap, but it have many useful options out of the box.
Wide and/or spot beam both about 5400K. Wide 95cri, spot 62cri;
Red light;
Stabilized brightness for all leds and modes thanks to some kind of step-down driver! (I am pleasantly surprised)
UI needs some polishing , but again its pretty usable.
Type-C charging port.
What to say more. It is kind of China made “Swiss knive” for ordinary user who newer had original one for good price . 
I think i will use it for biking.
