Theoretically one of the best lenses of the company. Unbreakable, waterproof, lightweight, powerful, with a brightness of 300 lm. In practice, it presented the same problem twice. Suddenly, the brightness dropped to a ridiculous level, like a Chinese toy. It was diagnosed as a LED malfunction and was replaced within the warranty. The second time it happened outside the warranty, so it was simply thrown in the recycling bin. Disappointing.

High price in relation to their capabilities.
It is waterproof for use in rain but not waterproof for submerging it in water.
