What did not work is the processing of the part, I shudder before the battery change because shows the weakness of the construction, although it could be the better solution. The AAA sit something of lax in the brackets, incredibly, by removing the silicone part and re-layering to mention. No extra cover. Viell keeps the batteries, or feathers on pole.
And then the packaging. Honestly, how can you just pack something so? You do not get on the packaging, without destroying them. The cardboard box is small. TESAS glued from the outside, ok. But then, the box is a paste with any adhesive, until no longer works. Why can not the normal pack in a box? The manual is glued to the box so that it is torn to shreds when you unpack. Something goes not, certainly not at the price!
Have not ordered a taillight, dasgeiche, of course, except that the part has not only works ...
