After a long search I bought this bicycle tail light. She is super value for money, especially because she was still so low. It is very bright, you should not see the light in, because otherwise one is blind for a while. She has two stages: 1x as blinking light and this flash only so through the area, which of course striking. Exactly one wants to achieve with it, to be easily seen when misted easily even in daylight. The meets this Taillight fully. Then it has a focal length of light, very bright, the batteries last for a long time -. I had so far they do not replace or recharge. An additional plus point: you can fix this lamp not only under the saddle, but it's also a holder for the pursuit on the rear wheel with the delivery. So you can fix this lamp either under saddle or on the strut. Since my previous taillights were swiped 3x, I remove in the future when parking my bike the light. This is also done very quickly and easily. You can also turn very easily, so that you have a little plan must be careful when you put them in the jacket pocket which she does not address this. This goes very quickly and easily. I am very pleased with this tail light.
