Bought it within 2 months the USB port has bent due to plugging in and out frequently - otherwise all is fine.
Beam thrown is rounded instead of projection style.
IMHO will not withstand rough use and should not titled Tactical or EDC item.
I really like this light. it is tiny, bright enough and you can charge it on the go. But it still uses micro usb which is really outdated.
