Deep Breathing Lung Exerciser, 3 Ball Incentive Spirometer, Washable and Hygienic Breath Measurement System, Package with Hygienic Seal

I was recommended one of these to try and clear phlegm from my chest and of my breathing. For the small gadget that it is it seems to work very good

I’ve been using the Respi-Ex Deep Breathing Lung Exerciser for a couple of weeks now, and I’m really impressed. It’s simple to use, but you can feel it working right away. I’ve noticed an improvement in my breathing and lung strength, especially during physical activity. Highly recommended for anyone recovering from illness, doing vocal training, or just wanting to improve lung capacity!

Does the job for me. Like another reviewer, I play the saxophone and wanted something to build up and maintain my lung capacity. For the price this is a grand bit of kit. Fairly sturdy and easy to use. Ticks all the boxes.

Bought for my husband who developed pneumonia in the summer. This is a good visual aid to practice deep breathing exercises. You suck rather than blow to raise the balls, this expands the lungs. The secret is to have them raise slowly and steadily rather than sharpener. 10 breaths every hour, it's a fun way to get someone to do it properly.

good and does what it says on the box

It has helped with my breathing

Poor quality control as the item was manufactured upside down/connected incorrectly when in comparison to the product photo so cannot be stood on a flat surface so unusable

I was recommended this product by a medical professional to help increase my VO2 max levels. I play saxophone and lungs capacity matters. The product literature recommends using it 10-12 times a day which I don't. It sits on my table and whenever I find time I use this
