The bulbs have been held three months of continuous use with me. I also ride the day often with light. So I can not confirm the high failure rate.
Since we / are early winter at the time in the fall, I now go accordingly often in the dark at a wet road. And here the Night Braker have unique weaknesses. The light color does not appear to be optimal. On a wet road, it seems to me as if I had to no light. That does not bother me that much that I still look around for an alternative for these bulbs.
