Charged by microusb, there are three levels of brightness.
Put on the phone and just shines - forward or backward.
Sharper photos by illuminating the autofocus and reducing shutter speed and ISO.
Possible applications for selfie and subject shooting like macro are far from enlightening.
It is written that it can shine 4-8 hours, you can use it as a flashlight with a wide light, for reading, for example.
A choice of 3 colors. Cord for charging from microusb as a gift. The price is valid 48 hours. Photos as always funny. cat
