Since I often at night on the Isar (Munich-Freising) going home, I'll be glad when I see small animals such as frogs or mice on the road in time and which may be diverted accordingly. Super is also the parking light function, in which the motto is: "You See". Well, if one is seen, but I think it's also important to be able see for themselves what. Such as the small Radschilder, often disappear in the state in the dark. The light can be given if even the floodlights turn with.
The difference between the 70 and 90Lux mode is not relevant but badly visible.
It's also nice the USB charging function. Although something you can feel the driving if there is a power-hungry at Dynamo tugging, but that is well able to absorb. After all, have to come from where the energy.
Processing the housing I find fine. Switch I'm not sure how long does the seal and the plug. I also feel that the jack contact at the lamp is not always optimal.
Who is a lot at night on unlit road routes, which I can absolutely recommend the model. Who is more on the town, the rich, the "Lumotec IQ Fly Senso Plus - 40Lux" models also offer excellent illumination. The CYO with 60Lux even light fantastic, but I found the parking lights for my purposes (read signs at night) just too weak.
The only drawback is probably that the whole lamp must be replaced in case of defective lamps - ecologically a pity. But perhaps it is possible to replace this with the U and the Luxos Luxos B because you according to B & M can replace the buffer battery. On the housing screws are present.
-> Use the models Luxos U, the Cyo Senso and the Fly Senso Plus. The latter two already more than 2 years and am very satisfied. However, I wanted a little more light and the charging function for treks for mobile and Navi.

-> Anti-Theft: Here you have, as with any lamp, himself think of something or as Pitlock (highly recommended) slightly down. Often it was enough exotsiche screws for unusual socket wrench that not everyone has the opportunity thief's hand. Stop bits are recommended in any case, because this can not just loosen up and down levers of light.
-> Charge function went well so far. However, have only a simple phone (Samsung BC2100). Has yet to test how well it goes with the buffer battery, as long as he can hold on the voltage level.
-> Something bothers me that a red light indicates the USB charging stand on buttons. At night this is a subtle reminder for thieves "there's something dolles". Do not know how long the afterglow when you stop. Made the switch a little hidden so.
-> Installation of the switch goes fast. Either with an O-ring or cable tie or both fixerbar.
-> Switch can be easily operated. Pressure point can be felt clearly.
-> Compared to the Fly and the Cyo it is really a plus. Not only the brightness but also the ready is super. M Going on occasion the surface measure. But it is great to detect obstacles early and to follow this up to the front. Even small animals like toads can then deliberately dodging. Who already likes to go dead with intent animals.
-> How long afterglow light which I have tested also, but for most traffic lights is sufficient (as in the other B & M models)
---> On the website of Busch and Müller can you look at the instructions for the light Download, ever to do quite well acquainted with few details.
