Mercury Medical Resistex Pep Therapy - Resistex Pep Therapy Device - MERC-1037000

When using RESISTEX breathing becomes more comfortable whether I'm congested or even a little wheezy. It's easy to carry in your pocket. It can be used even if you're not sick as a way to improve breathing as with exercise due to it's ability to increase lung capacity. I can use it to help relax me at bed time and before I know it I'm dozing off. It can be used in any position unlike some of the other devices that need to be used at a specified angle. I find RESISTEX to be a simple, easy to use with very few parts, very versatile and much less expensive than many of the other ones. Thank you
