Flutter Valve Mucus Removal Device Natural Mucus Clearance Device with 19mm

Wow! Was I ever greatly pleased when I received this. Much easier to use than I thought it would be also; better pricing than the ones I looked at like they had in hospital. Cheapest most well built product I've ever purchased. Easy to use and can actually feel my lungs getting better, stronger. Helps really well with my copd with keeping my lungs clean and open. Unbelievably easy to clean, use get results from. My lungs thank you ever so much I thank you for an increased ability to breathe.

It works. When I use it, it makes my chest rattle and helps get the gunk out. It's a good investment.

Sturdy product, good price. Simplicity, and better than the more fancier expansion devices!

I wasn’t expecting much but it really works! Improved my breathing in one day. After three days of use, I’ve been able to cut my inhaled steroid use by 50%. Outstanding instructions. The quality of the device itself is very good. It’s constructed with a high quality thick plastic, fees almost like Lexan. Very easy to disassemble and clean.

I have used these before, but not yours, but I love it that you have a cover for the mouth piece, and a zip pouch to keep germs away, keep up the good work,

This works somewhat for helping to loosen phlam
