I need a bike light, I spent 2 weeks investigating in Internet and seeing reviews from another customer. Finally most of the owners recommend this model. Actually is really good, easy to wear on your bike, shiny light, beautiful design, long batteries and no mention How great is charge it using your laptop or CPU. The only BUT, the price is too high (normally for all bike lights) but in compare with the rest of the offers this is the best one. I hope the money spent on that really deserve it along the time.
