Very satisfied with this product, shipped quickly, I recommend it. For fifty euros, it seems to be of very good material, sturdy and attractive and a very satisfying light output. Not having only a few weeks, so I have no opinion on its reliability but this lamp has very good press on several websites. There are 2 main positions: one for full power + strobe mode (to use only on ill-intentioned people, it hurts the eyes!) - The other for 3 lighting modes + SOS One changes position by turning the lamp head and pressure by way of changing the switch to the "bottom" of the lamp. It is embattled and can therefore serve as defense tool such kubotan. However, the mounting bracket is too hard, I think it is useless. The small pouch supplied is fine but I have doubts about its life. When I hold it in my hand - on / off with your thumb - it hardly exceeds the other end, so it's almost a little small for big paws but it is not annoying. This small size is also very significant. Finally, it operates on a single battery LR6 widespread, cheap, it is still a very good point. Very pleased with this purchase.
