I've only had time to use it once, but based on that it seemed like a really good purchase. Based on tips and recommendations, I bought it as a mask light for freediving. Suitably small and also efficient with batteries.
Very good, really small and bright diving light. Especially suitable for freediving very well.
Good handy spare light for many uses. Waterproof and durable, so it is suitable for many uses other than water sports.
Good and bright light. The dry gloves are a bit small but don't take up much space in your pocket.
Good brightness, but the size even unnecessarily small, quite wide beam.
