Just follow the instructions and
Just follow the instructions and your all set. It gets uncomfortable after a long while but adjusting help improve the comfort. The back of the unit seems to get warm after long usage don't know that's normal. Work great with my VR games like Synth riders, Gran Turismo, and Population one. Works very nice with my Music and Movies. Feels like your in a car with a subwoofer and Imax movie theater. Wish the side of the unit was little bit longer but overall great Vest. Shipping was pricey thought the shipping would be free.
