Flutter Valve Device for Lungs, Breathing Exercise Devicefor Lungs, Adjustable Resistance for Natural Mucus Removal, Portable Lung Exerciser Device | Breathing Trainer

Good, compact device that actually increases your spirometry. Three different ball sizes that gradually increases the resistance. Good value.

Easy to use and works!!!

Really helped with some breathing problems and loosening up mucus build up getting over a recent cold. Keeping this as part of my get over a cold treatment

Works pretty good, price was good!

got it for a family member with COPD who was having trouble clearing mucus and having subsequent coughing fits trying to clear up. He says it feels like it's helping separate the mucus and he's coughing less, and it was easy to clean and get started with.

The seller did a poor job of inspecting their product before shipping. Two of the three balls were missing and the box was crushed but the contents were undamaged. I checked to see about getting the missing items shipped, rather than do a return, but that wasn't possible. So, I tried the product to see if it was worth the bother. I think my unit came with the largest pellet and I can't say whether it works or not. It may loosen chest congestion so that it can be coughed up easier. This unit this isn't worth the asking price but it was the least expensive to experiment with. Three pieces of molded plastic and three SS bearing that cost a total of a buck. And my experiment's result if inconclusive. If you have a congestion issue and are curious, I would look for another, better made version from a different seller.

Very beneficial in trying to strengthen my lungs.

Easy to use and really helps with my breathing issues. Great price as well!

Fena değil, iş görüyor. Uygun olduğu takdirde alınabilir.
