I have the SX 25 since mid-2013 and can only report positive. It is well processed. As a tactical lamp possesses several light modes, which can be found in the manual. Those who thus looks something has quickly discovered how they work. The lamp is supplied with 2 charging options (car and 220 V AC). Charging takes, depending on the discharge, about 2-3 hours. After switching on the respective luminosity indicates a blue light-emitting diode, if the current stage enough juice is still present. If not, then they will turn red, and you can do is to select the next lower level. Until then, take a long time because the batteries are very powerful. The lamp is located by the harsh battery tube very well in the hand, but you should use a wrist strap to prevent unnecessary damage. Weight and balance are also for woman hands (which are usually smaller) very suitable. Who (actually enough) would like to improve the range, can be a turbo head for a good 40, - order. Now something for "Range Freaks": The specified range is specified with 377m. Honestly, who needs more than 200m? From a distance you can hardly recognize certain persons and objects anyway. There are lights that come twice as far, but also cost 3 times as much. So keep your degree, because no upper limits. A Safety note: Please charge the battery only in the composite lamp and disassemble, which could be a problem with the guarantee. People who buy this lamp, sure has a lot of fun with it. My Kauftip with 5 stars.
