adjustable lighting on top (not tested recording programs because ... I do not see the point), reliable for me: a night trail 3 hours in low brightness adjustable lighting (but .. . illuminates almost as day anyway): it remains 2 light load witnesses :) 2 small negatives: 1 / fogging we exhale disorients the adjustable lighting that is believed to be facing a reflecting wall and hit rate is now less intense, sometimes you blow on the side;) 2 / bearable weight on the head (precise setting possible), but the top is still using the kit to place the battery in the bag , on a belt or in a pocket of course, the kit is optional ... Paying, of course; but taking advantage of specials, it's still very good value for money !!
