Yep, take the time and tools to find the sweet spot. In the wrong position it's REALLY bad in in the proper spot for your height it works very well. Takes most of the pressure off your chest. I got mine right by riding and using my left hand to feel the air flow (or not) and that helped find the right spot. Took me about 2 days on and off. I'd ride for a hour and than adjust, ect.
