The launcher does not come with instructions, making it very difficult to adjust it properly. Until now, one month after purchase, I have not been able to confidently find its settings. When I put it on the arrow indicator, it does not function as shown on the switch. I turn the switch until I find approximately the setting that suits me, always blindly. I would not buy this particular product again because this lack of instructions makes it useless. Next time, I will prefer a launcher that can be adjusted differently or that comes with instructions.
