Have decided after a long search for this light because I was looking for a fast to be mounted tail light with good light output and standard batteries for the bicycle trailer. Light was mounted really easy and fast, brightness also convinced, so far everything well. A plus would be a flashing function. After 3-4 inserts I could not turn on the light, but it turned later himself, then stopped going off. Even after repeated opening, battery replacement and maintenance is doing nothing. Pity! Hopefully an isolated incident!
