The headlamp has been able to impress me with aussließlich good qualities. It is comfortable to wear, as can adjust the headband and it is also very easy. It fits well with a very large head shape even without pressing! The operation is easy and reliable. The supplied battery charger and the right round out the product perfectly. Quasi unpack - charge - and there you go! Even a simplified form of "Battery level indicator" is that warns when the battery when you turn an already only 50% and has 25% of charge. And now for the most important of the lamp: yes, she makes light. I have used them in the forest and give bright shining green light for use while walking, running, geocaching, etc. The beam is focussed by strong and extremely bright wide to generous open and still very bright adjustable. Really all it takes! Strong buy recommendation!
