I have never been faster for setting a bezel 3 shots and that's pil hair I have already be paid much more expensive that were much more boring to adjust I'm very happy with this purchase cheap which seem to me to be the gadget I shoot a lot at night on rats who took over I was aiming with a red dot but frightened rat and 20 meters I'm 5 mm of the fly so it's all good I strongly advise the quality is decent and effectiveness is to go that price is tip top and it's not enough for me worth spending 250 euros
