Teleflex Medical 8884717301 Triflo II Inspiratory Exerciser, Deep Breathe

Though the picture shows this product slightly differently than the others I've seen online, I got lucky!It's exactly the same as all other TriFlo II's in person, it's listed cheaper than anywhere else, AND qualifies for Prime Shipping. Love it!Get it while you can.

Product works as expected. Purchased for wife at doctor's recommendation for breathing exercises. When I proved in lung capacity in just a short while of consistent daily use. Very happy with item.
