I purchased this product a few months ago and I find it perfect. Adept PETZL for twenty years in the context of my work, I had never been "far" the basic models of the brand, also very satisfactory although limited in light output. Here it is clearly within another dimension. Indeed, I walk, I run and I sometimes ride the night and this lamp allows me to keep a rhythm "cruise" even when the light is not at the rendezvous. This is, in my opinion one of the best quality-price ratios of the brand, with a still affordable. Of course there are more powerful, but also much more expensive (double) with an expensive rechargeable battery system (the price of a battery is almost the same as the MYO). When you are passionate amateur sport and that we do not have a personalized support, we must make choices. This one seems to be best suited.
