I can only recommend this flashlight. It is very robust and well not to force in normal use in the knee. The brightness can be compared with any other flashlight, which I had so far. You can, thanks to the adjustment between "area lighting and spot lighting child's play and go continuously back and forth. So you can even quite groflächige areas illuminate, or, on single points shine brightly at a great distance.
The mix of luminosity and processing is the big plus of this product. Can recommend it to anyone who is looking for a durable flashlight!
