Flutter Valve Device for Lungs, Breathing Exercise Device, Adjustable Resistance Breathing Trainer for Natural Mucus(Strong)

Found this after my doctor recommended it to assist with my lung function. Easy to use. Good video on how to clean. Clear instructions and a good value. Well Designed an made with high quality.

Great product - I feel better even after a few days of using it. Helped clear up my cough. Cleaning it is very easy too.

I had fewer expectations from this but have a good impression of this product. Well built product and works great for the exercise and drug-free mucus removal needs. My 2 cents below: Pros: - Works great as a exercise device and mucus removal while being drug-free - Has an adjustable resistance dial to control the intensity as per the needs - Easy to use - Works without any battery - Very small in size and portable if you want to take it anywhere with you - Seems very durable Cons: - Not the most reasonably priced but would recommend for the quality and functionality

Easy and effective to use. Therapist says it's a great way to improve lung function by helping to clear excess carbon dioxide that can accumulate with shallow breathing.

Very durable and functional. I had a different device for many years and this works a treat better!

It arrived in excellent condition and is a very good product. I recommend buying it, it works very well.

REVISED: THE COMPANY REACHED OUT TO ME (AFTER AMAZON 30 DAY REFUND POLICY EXPIRED). THEY WORKED WITH ME TO HELP ME UNDERSTAND MY DEVICE AND HOW TO USE IT, PLUS THEY SENT A REPLACEMENT. THEY WERE VERY PRO-ACTIVE IN COMMUNICATING UNITL I WAS SATISFIED. THE PRODUCT IS A LITTLE TEMPER MENTAL TO RE ACTIVATE AFTER CLEANING, BUT IT DEFINITELY IMPROVES MY LUNG CAPACITY. OLD REVIEW: " Very discouraging. It worked for less than a month. I neglected to return it, because I kept thinking I was doing something wrong/ After cleaning, could never get the rocker on "just right", and barely get any vibration at all. For the money, it should last longer. I can tell a difference in my lung function since it quit working. So it was helping, as long as it worked."

This breathing exercise device is well-made, easy to use, and perfect for anyone wanting to support more comfortable breathing. Its vibrating airflow design helps loosen mucus and makes each breath feel smoother. The adjustable resistance dial is a great touch, allowing you to tailor your breathing sessions to your own comfort and training goals. The build quality is excellent—made from durable, medical-grade materials that are easy to clean and built to last. I also appreciate that it’s completely drug-free, requires no batteries, and is compact enough to take anywhere. Whether you’re into sports, doing breathing exercises at home, or just want a simple tool to support better airflow, this device offers a practical and user-friendly solution.
