Mucus Clearance and Lung Expansion Device, Flutter Valve Mucus Removal Device, Lung Exerciser Device for Lung Strengthener, Breathing Exercise Device for Lungs (Light Blue)

I ordered this product when I had a cold/cough that wouldn't go away! The congestion was not eased by any over-the-counter remedy I tried. Then, after using this device only once, it immediately brought up some of that mucus and made my cough productive! It takes a little practice, as it forces you to breathe in a different way, but it really does work. There are 3 sized metal balls so you can choose the one that's best for you. It's easy to disassemble & clean. Also has a nice, velvet drawstring pouch so you can take it to travel. Definitely worth the cost!!

I purchased the FlutterValve Valve Device in September 2024 and have been using it since. It really is so simple to use but very effective as well. Since then, my lung issue has improved and I would highly recommend this product.

I've been having bouts of severe coughing every night for over a month, and I came across this product and decided to buy it.Wow! Instead of coughing and trying to clear my throat, using this device helps gather the mucus. It really works.After coughing, my throat would get scratched, my muscles would ache, and I would feel exhausted, but now I just need to blow into this device with force, which is so convenient. However, it can get tiring if you blow for too long.The cleaning is simple, and the design is sleek, so I'm very satisfied.I find the medium size (out of the three) to be the best fit for me. I've recommended it to two other families as well.

It really does work. It's very effective. It looses phlegm and allows me to rid it from my body. I would definitely recommend it.

This is a wonderful product. My doctor told me to get this and it has done wonders, I can breathe a little better.

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.

This Lung Exerciser is a product of a very good quality made from solid thick plastic with heavy metal balls. Very easy to use and clean. Helped to break up and clear mucous. Highly recommend this to anyone needing an Flutter Device.

This item is high quality, and made of durable material. The design is compact and easy to take on the go. I bought it for my husband to help loosen the thick mucus in his chest. I highly recommend this product to anyone suffering from excess mucus, or anyone in need of lung training and expansion.
