Flashlight has nice feel and looks good quality.
Threads are square but little thin. They are anodised and came well lubricated.
Tube is not reversable.
Tail switch is reverse clicky mounted on 17mm board. It has nice click, but maybe little soft feeling (very easy to press, compared to others)
Flashlight can tailstand, but was not perfect na was wobbly. I cut 1mm from center of rubber tailcap and now perfect.
Driver is 19mm, but you could put 21mm with no problem. It's fixed with retaining ring.
Wires to LED are 24AWG
It has 4 modes with memory and strobe on double click. Modes are nicely spread.
Head has SS bezel. Glass is 27x2mm AR coated and reflector is SMO. AR coating is very light, but it's there.
There is o-ring between glass nad reflector and reflector has groove for o-ring to sit nicely.
LED is XP-L2 and is on 17x1,6mm copper board.
There is 1 screw holding board to shelf. Shelf is fixed, so no pill.
There is good amound of thermal paste between board and shelf.
Flashlight is 132mm long, diameter is 25,5mm at tail and 32,5mm at head.
Beam has some rings in it, not sure what is the reason.
Charger is Thorfire branded, with micro USB input.
It charges to 4.19V (if my multimeter is correct).
Battery is Sofirn branded, with protection. It came with protection sticker on + side.
Tested capacity with Lii-500 is 2628mAh so not that bad.
Some comparison pictures with Thorefire VG10 and Convoy S2+
Current measurements:
Cheap dmm, not sure how accurate it is so I made measurements on some other flashlights to compare.
