Almost perfect - Streamlight ProTac 90X Right Angle Multi-Fuel 1000 Lumen LED Tactical Flashlight

I'd give it 4.5 stars from minor complaints but it is my favorite light and the one i use the most

I like the 90 degree angle and I was always against it until I bought it. Now I need to have it.
The size is compact and fits well in my hand and in my pocket
The battery is rechargeable but minor complaint is that I have to remove it to recharge it but...
That means I can replace the battery of it dies and...
There is no usb port or holes for water to leak inside it
The pocket clip is removable and it works upward and downward which is becoming the standard for pocket clips
But... Minor complaint is that it scratched the paint a little bit

You can half press the button for temporary light. And full press to keep it on like normal.
Its programmable for low, high and strobe but i keep mine on high.
Low could be useful but not for my applications.
Strobe is useless to me.
