BUT:
B & M is one of the best known and most renowned bicycle lights manufacturers.
Have as developer or hobbyist engineers?
For arrival and issue: hold button long.
Light modes switch: Press the button briefly.
All make it easy but B & M chooses the circumstantial method.
Cryptic flashes show me the battery level. Since I have not yet learned the Morse code by heart, I must take the instruction manual in the future. A red LED would have done.
Waterproof?
Since I have grave doubts. The rear rubber seal to close the connector slot goes from the beginning again and again. Absurdly, she goes up to (rain always step inside). You would be closed down meaningful.
The handlebar bracket:
Please, please, love B & M developers tried but every time to get in the dark, the lamp into the holder.
Those who manage less than 10 minutes has won. In 5C outside temperature mitklammen fingers the challenge is even greater.
The lamp has to be inserted from the side into a mini slot. Something Hake Liges I've never experienced. Hit or miss when it suits. Do not simply postpone the lamp from the rear of a large shoe, as the cheap lamps from China to themselves.
The assembly is a joke, a rubber is stretched around the handlebars to the holder. We'll see when it is porous and the lamp flies away.
That's naughty in this price range.
Amazon here represents another holder, when I got it, maybe that has changed.
