Flashlights, good if you have some. Or one or two good at least. As I have ever bought a black LED Maglite years ago (2x mono batteries), I know how high Maglites are processed. This blue small I shot as flash range. I did not know that Maglites may be technically so exciting already. The functions you quickly plan. You will most often need, but cool that they are possible. ;-) Feels great in the hand, does not roll on a reasonably flat table away also because the housing times has grooves and is sometimes smooth. I am very satisfied. Can only nothing to say to durability of batteries in principle. Uncertain I'm still in the recommendation that one should feed the thread and rubber parts with Vaseline. I used WD40, I am open to advice. Great flashlight with Gyro Gearloose, almost James Bond flair. :-) Brilliant!
