Simple to install and use. I installed it on a 35+ Deuter bag smoothly with a Pentax K5 + 18-55mm zoom. First exit: 70 km on the roads of the Tour des Glaciers de la Vanoise! No problem with that system. The camera does not move, even on very rough roads and does not impede walking, even with sticks. What a pleasure not to have to leave the device the backpack every 5 minutes or to have bruised shot by the strap !! Frankly, I regret not having bought earlier ...
