I had ordered because of the good reviews for the brightness, because I wanted a bright lamp for my dog evening walks. The aluminum housing appeared robust me, so that I thought the ideal flashlight. If it slides time out of his hand and landed in the dirt, it is not the same broken. The expressor is bright, no question, but it is also difficult. Whether it makes 180 lumen, as is in the title, I do not know, in the description is comically 150 lumens and that it has an end cap. The latter is rubbish, the operation is, as can be seen also in the picture, a small button near the front. Caution, the jammed very quickly. When you first try it remained at 3.Mal on / off hanging and I could not get the light on! With a bit of back and forth, he was then out again. Also not as optimally solved I find the battery. He makes quite weight and it is not a commercially available battery. Good that the charger is included. The SOS flashing light is not a signal SOS! It's more of a flicker bombing! All in all, the flashlight okay, but nothing earth shattering. Compelling brightness I'll keep them. For 16, - Euro, it is acceptable, but for a 10 more you get quite a MAG (eg XL50). That is not so bright, but in handling a lot better and it is not half as difficult! I have my way, ordered the same!
