I also appreciate the sturdy, medical-grade PC material—it feels durable and well-made. Plus, the transparent design is handy for visually tracking progress during use.I’ve found that using it for a few minutes each day has made me more mindful of my breathing technique.

For the last three months I've been dealing with lung inflammation from radiation treatments and breathing and congestion has been difficult. I was quite concerned from the symptoms I had that I was possibly experiencing advanced COPD instead. I had read about the effectiveness of flutter valve devices and decided I'd give this device a try, and the price seemed very reasonable. I was surprised at how effectively it worked... I got the best results from using the largest steel ball, and about twenty minutes after using it I would cough up a lot of junk that I normally couldn't. It seemed to work by subtly vibrating my lungs as I blew into it, which loosened phlegm. As I've continued to recover from the inflammation I'm not needing to use it as much as I was initially, but I recommend this device to anyone dealing with lung issues that cause congestion. It's very easy to use and it's small enough to carry in a pocket.

I bought this device to help improve my lung capacity and clear out some lingering congestion—and I’m honestly impressed! It’s lightweight, easy to use, and comes with helpful accessories to tailor your breathing sessions. After just a few days, I could already feel a difference in how deeply I could breathe. It’s a great tool for anyone looking to boost lung health, recover after illness, or just improve their overall respiratory function. Highly recommend!

This product is a great value, considering other options out there.It feels like a quality device - all the parts fit nicely together, and so far, it's durable. The options for the different balls is great to change the resistance. It's easy to clean, and comes with clear instructions.

The product is well constructed. This is not a flimsy device. Easily cleaned . The exercise is very simple but it is effective . After using the device my normally quiet voice is stronger . The device is pricey but effective .

I’ve been struggling with an active cough for almost 8 months. I saw a pulmonologist who suggested this “flutter valve”. I ordered it not fully knowing what to do with it. Instructions were spot on. I’ve been using it daily for a month. It is doing its job. When I use it, it helps me clear my lungs of the mucus that’s causing my cough and am breathing much more easily.
