This flashlight has it all. Relatively small it appears so, but the light output is to use very well. 4 switching stages and 3 tactical (Strobe, SOS, flash) I operate with a 18650 battery from the same manufacturer (2600 mAh) by holding very well. The length of 15cm know you appreciate, if it is to disappear in the jacket. The handling improved with the installation of the supplied Wegrollschutzes (fits only once). The battery status can be checked at the side switch (see operating instructions in English only). It has a memory function that the last shift stage remembers the datum. The price between 60 and 70, - is okay. I have already had lamps in their hands, which were more expensive, but not nearly the performance and equipment had (LED Lenser and Co.). This lamp is on top of that waterproof to 1.5m, but you'd never have to try it, but pouring rain makes her nothing. The supplied spare parts (lanyard, 2 sealing rings, Spare button, clip are also a nice feature. Conclusion: Small lamps with Bumms Good Buy rating..
