I have been using the original Keysmart since I got it back in March 2017. The idea of organized keys is not new, but KeySmart nailed the execution.
As I was impressed by it, I even bought Li Xiang a Black KeySmart after using mine for a month.
It is a small LED torch light that is made from stainless steel, and the LED is made by NICHIA. The LED provides 25 lumens of light output.
KeySmart is a compact key holder that can hold between 2 to 8 keys (or up to 100 keys with expansion packs). It will fit any keys of length up to 8cm. Because of the way it is designed, it will eliminate any key jingle when it is in your pockets.
