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.

The AiraVentus Flutter Valve has really help with my breathing over time. I particularly like the adjustable resistance which allowed me to start at an easier setting and then allowed me to move up as my breathing improved. Also, unlike other valves, it is very easy to disassemble and clean in just a few minutes. It has been very effective in helping me to loosen and clear mucus. Definitely a high value product.

ALL the information on the Flutter Valve was true to its last words. Great quality, easy to understand directions and ease of use. You can tell it will last a long time from the material it's made from. The price was great. I would definitely recommend it.

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

This flutter valve device works great. I use it 2-3 times a day to help break up mucus and increase the inhalation and exhalation of my lungs. It has really helped my breathing and reduced my COPD symptoms. It’s very easy to use and is a super form of breathing exerciser.

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

This flutter valve device works well. The only problem I've had is taking it apart to clean it. I've got arthritis in my hands, so I've struggled, but it does seem to be loosening up and getting a little easier.

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."
