Very good battery life, good illumination, holder does not make professional impression.

First of all the most important. The strongest brightness is anegeben with 70 Lux and will be achieved with the 5 and strongest level. What can we say here, you can see everything clearly on a Fedweg to 30-40 meters and can until at least 50 meters in advance recognize what comes to one. So keep a sufficient time to an obstacle or what to avoid always.

Battery life is at level 5 at about 6 hours. That's a long time, half a night to go to the highest brightness level)))
And even after that is a long time do not give up the ghost, it is only forwarded one step down, so step 4 .... and so it goes on .... theoritisch you have to be an idiot to deal with this lamp at night without Light to stay.

Battery charging takes place either via USB to the PC / laptop or USB charger to the wall socket. I myself charging it simple by USB on laptop, but charging takes around 10 hours. With current USB adapter it is already 3.5-hour charge.

Design is a matter of opinion, however, I find the lamp of her design very modern.

The lamp seems to be very robust, because nothing wobbles and it feels like a stone, I think it is not so easy to get broken;)

The bracket is probably the only weak point, hitherto everything works just fine, but the time will show if it proves itself or causing problems.
Because I lack long-term experience, I did not want to take away the 5 star rating for this unconfirmed thing the lamp.

Therefore 5 stars. gel ???
