This device provides an added benefit to airway clearance! The flutter device works and can be clearly felt in intensity in your chest as you move the dial. Been using the device for over a year now and recommend if looking for increased airway quality. Note: Be careful with disassembling to clean. The flutter component has two small protrusions that can easily break rendering it unusable.

I wasn’t sure what to expect with this, but it turned out to be a really nice little gadget. It’s simple, lightweight, and doesn’t take up much space at all. I like that it has adjustable settings so you can switch things up depending on how you want to use it. The quality feels solid, not cheap, and it’s easy to keep clean. Overall, it’s a handy little gadget that does exactly what I hoped for. If you’re looking for something simple, durable, and easy to use on a regular basis, this one is worth picking up. Very functional.

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."

Product arrived faster than advertised. Is well made and does what it's supposed to.
