Positives: The luminosity is actually not bad and the burn time (about 3.5 hours at 40 lux) is decent. The illumination is for pure use on the road in order.
But: The lamp just ran the first two / three months without any problems, then she began to not quite level ground to flicker and finally switched easily from. During the trip, she was no longer to get. So complained. Unfortunately, it was the second time no better. Now I have the third, which lies almost exclusively around because I have no desire to sudden dark rides.
Somehow there's a problem with the contacts that are susceptible to simple. And my case is not an isolated case, that can be read in various Radforen.
In addition, the holder mE is undersized and not optimally designed. Once the asphalt is bad or there is cobblestone, I have my hand in addition to the lamp, because I'm afraid that the support from the handlebar triggers. The quick release simply does not hold true, at least in the my Syntace 26,0mm handlebars.
I hope that this BOOM (not really new) can fix deficiencies, until it gets a really good product.
