With this product it is a true happiness really we see very well, even in automatic mode. When power mode "full brightness" is almost as bright as day!
The front is set by default to automatically adapt to ambient light and reduces or increases the light. This is very useful and it helps to avoid dazzling cross people. Moreover the program allows you to customize the various modes and works well.
Finally autonomy is very good; I've raced over 4 h and I'm only 50% of the discharge level.
The only flaws:
- The program (on Mac) is capricious and does not launch twice if we did not re started his computer.
- The fastening system around the head is a bit complicated to adjust especially when you're on the run; a race to the other it tends to relax a bit
