Small lamp with a high value

Flashlights are for me as a handyman and winter joggers always particularly important, so I was curious about this small waterproof little device. Here's my opinion:
- Very high-quality housing, which probably survived a fall (just my two daughters are just so in the house on the road)
- Very bright cold light, we could try (looked for and found nightcache) in our winter evening hike
- I was a bit surprised by the required batteries, which probably not everyone in the household: CR 123 (CR17345) 3V needed, or even better batteries
-'m Curious if the lamp also survives small dives, rain has not harmed her but
Conclusion: Due to the rather small size I have now participated in all sports activities in the dark.
