Where to begin?
The design Is a home run, the material use now is great. I have the stainless steel & aluminium version but this one is definitely my user and favo. The double click to activate is such a great feature, no need for an lockout.
The user interface is great, the output is just amazing. Because of being titanium it doenst handle heet well even at 650 lumens after 5 min it does get hot. At 4k lumens you can smell the Titanium when using the light it gets that hot, only thing I need is an battery indicator to see what the battery lvl us during use and this is a must imo on a good high end production flashlight.
Get this light you won't be disappointed!
