David ★★★★★ Aug 22, 2026

Took it out of the box and clipped it to my keys—for something this small, 500 lumens is honestly ridiculous. The single switch is easy to find in the dark, and I’ve already used it to dig through my bag twice tonight.

Leo ★★★★★ Aug 21, 2026

The single switch cycles through seven modes without any fuss, and even the lowest setting is plenty for finding a keyhole in the dark. Charging is dead simple via USB-C, and it's so small I forget it's clipped to my bag until I need it.

I keep it on my keys and the 500 lumens actually lit up my whole hallway during a power outage, which is wild for something this tiny. Charges through USB and holds the charge for weeks, so it's one less thing I have to worry about.
