Fast delivery - as usually at Amazon. After unpacking, I note that the headband is involved. To unravel it, I have to take it off, which without problems is possible, but for the subsequent re-attachment I need some patience and tact. But I can also be sure then that the straps are securely fastened. The shortening of the ligaments in my head shape is simple.
By the way you can use the headlamp without upper headband. Therefore, the cable is not routed over the headband, which from a Mitrezensenten - m. M. wrongly - was criticized. It allows me to the headlamp (with and without headgear) under a hat - helmet, etc. - bear.
A set even to the cable: It is relatively thick and is very durable.
Headlamp and battery compartment are well padded so that the wearing comfort is very pleasant.
At first, the opening of the battery compartment seems difficult and pictorial instruction is not clear to me enough is enough and the writing of the manual is kundenunfreundlich very small. Eventually I get the battery compartment open with the pressure applied to him Note: Do not pull but rotate the tray counterclockwise. After opening shows that was really thought along in the design even in small things: The lid is secured before the fall down through a connection to the battery compartment. The closing of the subject is - if you have understood the times of closure - as easy as opening.
The battery compartment is located at the back and has a red LED integrated. The red LED in addition to the headlamp with a separate switch on Battteriefach be switched on and are thereby selectively set to fixed or flashing. This one is well visible in the dark.
The front light can be used in three different modes. The "Manual", consisting of a piece of paper with very small fonts is improved. Not only the small font is to be criticized, the entire section is in need of improvement. I was certainly not make sense of the instructions on how I can use these three modes. But, and this reconciled me again, the producer came forward to an e-mail quickly and told me to use and understandable. [For those who like do "stupid" to. To get from the first to the second mode, you have to quickly press a second time on the shift knob and for the 3rd mode you just have to press three times on power (1 modes). But is a mode selected, then the lamp will then pushing off.
Previously holding the first batteries yet. Since I did not stop the time, I can only say emotionally that the manufacturer's instructions seem to agree on its website: Battery burn time Headlamp: HIGH '8 h (ANSI FL1). LEDs (white) '40 hours (ANSI FL1). SOS FLASHING (white) '100 hrs .; LED (red) '120 hrs .; FLASHING (red) '180 hours
The motion sensor is designed to be 10 cm, this is to prevent that you switch the lamp on or off accidentally. Happened to me anyway that one time or another, as I quickly walked close to a subject.
I myself do not really need the motion sensor. I still often use the lamp in this mode is that the brightest setting in mode 1, ie with movement sensor. It is true that usually extends the brightness of the other two modes, but I prefer like the brightest light.
Anyway, I use now the headlamp very much and do not want to miss it.
Conclusion: Those who value quality and want a headlamp that is suitable for both everyday and for more extreme situations, 121 sensor is operated excellently with the Liberty. For what you get the price is ok. Who can do without Bewegunssensor, should look at the other models of the manufacturer.
