Summary
The Sofirn SC13 is a small and lightweight EDC flashlight with a creative design. The waist and texture feel very nice in the hand and allow for a reliable grip. Sofirn did everything right with the UI: It is simple, has shortcuts to lowest, highest and last used brightness and no unnecessary features.
Not sure if there is any benefit from the fancy Fresnel optic. The beam has a smooth spot with some small rings in the spill. Unfortunately the tint is not the best: slightly green with a noticeable tint shift between spot and spill. But for most users it should be acceptable.
