Incentive Spirometer Adult, Lung Exerciser Device, Breathing Trainer - 6000ML Inhale Volume Measurement, Equipped with Ball Flow Rate Indicator & Scale Indicator

Due to fluid in my lungs my doctor suggested using a Spirometer. I found this one that had great reviews and a great price. It’s very lightweight and durable. The directions were very easy to understand and within a week my fluid cleared up! Highly recommended!

Works great and provides measurable feedback to breathing capacity. I keep it by the bed and use it several times a day.

I'm getting ready to go in for surgery. And the doctor wants me using this to build up my lung strength. And I can see a big difference already..

Good quality! Helped my wife get through breathing therapy after surgery.

I ordered this as I needed one for post surgery use. I have been using it at home before surgery and it is working well

Seems very durable. Reasonable priced. It's very easy to use. Simple device to train my lungs. If you have lung condition and just need to exercise the lungs, this is your device. This has a good design, it is comfortable to handle and not heavy at all very light.

I bought this following a surgery and found it very helpful for doing my breathing practice.

Wonderful. Ready to use. Nearly silent. Smooth. Perfect really. No weird smells.Much better than this other one I bought on Amazon that had 3 balls in it and got fur and junk in it all the time and didn't work as well to keep the inhale steady.
