The naïve man hopes a single time to buy a good, durable lamp for everyday life and then to have on the sector rest for years. The T10S also looks really good, feels good in my hand, makes a memorable impression of high quality. The commercially available battery was to change my usage behavior every few weeks times. The dark firefly mode is ideal for night walks, because you thus largely replaced by the dark adaptation of the eyes. The clip-on diffuser is a real added value, because it makes it possible to illuminate a room evenly. The brightness control of LED is not done via simple pulse width modulation, ie the light flickers not, but looks absolutely uniform for my eye. Unfortunately, the positive external values of a product can but to not say anything about the actual longevity of the entire system.
I have the lamp used regularly in the dark half of the year for being clearly visible as a pedestrian on dimly lit paths for any bicycle and automobile traffic. In direct comparison to the funzeligen old flashlight, which I used before, which was also a great success: motorists stopped on highways suddenly respectful distance.
Around nine months after the purchase of Tailswitch slight signs of loose contact began to show. Meanwhile, eleven months after the purchase, it is a matter of luck, when the lamp is at all still turn on, or if it remains then also switched on.
Perhaps I have simply been unlucky with my copy. Perhaps the life of the factory is actually calculated only for one year. Maybe I'll find a way to repair the switch miraculously. Perhaps other versions of the lamp are more durable. Maybe I'll find out how here there is a warranty or a warranty claim.
A smaller, more predictable weak point is the belt clip, the screws come loose every few weeks. Once you realize that the clip is shaking, you should immediately pick up the supplied Innensechskantschlüsselchen and tighten the little screw, otherwise the amount of wobble is exponentially harder. If you want it absolutely maintenance-free, should refrain from the belt clip.
Overall, it would be in everyday life in civilization is not necessary to buy the version with the steel case - unless you know beforehand that you will be regularly roll with a jeep about it! In principle, I am happy in spite of everything, and going to buy another spare T10, now in the cheaper aluminum variant. In this I will spare the mechanical limit switches by I'll use it alone as a transport lock to prevent accidental switching. For mode change and the rapid short light requirements go I will turn the lamp head.
Finally, a pious wish ans ThruNite product management: A sleek, unfussy T10S-like lamp, perhaps with space for two AA batteries for the purpose felt endless burn time, but above all an additional differently colored LED (red or green), I would buy very soon.
