NIVJA Deep Breathing Lung Exerciser, One ball Incentive Spirometer, Breathing Trainer for Strong Lungs, Inspiratory Expiratory Muscle Trainer, Hygenic Seal

Good for the right person. I returned this.

Good bit of kit

Getting older and weighing more than I should, means I often get short of breath. I know I need to accept this age thing - still in my 20s inside, body of a man in his 70s though !!! - and as there is no magic wand available to help, it is all down to me. I therefore have to knuckle down and lose weight and get fitter.I thought I would try this as it might, just might help a little. After using it for a few days, I think I can already feel some benefit - early days yet - but already the indicator is showing some improvement. I shall keep on using it.The Spirometer is plastic, but well made and tough enough to do the job it is designed for. It is not expensive at all and could be of a lot of help for a lot of people, me included. I have never really smoked - tried a bit when younger for a while, never really could see the point - and so I feel my breathing problems are about age and lack of exercise and weight. Down to me then.As I say, after just a few days I have noticed some slight improvement. In my opinion this is worth a try.

It will help but I think you need to use it alot I can't say if it work for me because i am on a different inhaler but I feel a lot better but I can't say it work need more time do another review

Rather cheap plastic. The idea might be OK but I haven't seen improvement

Strengthen and build up lung capacity

A junk! Cheap material. Not working as intended.

Good quality easy enough to use it's worked well for me seem to have expanded my lungs I'm not as breathless now I think its worth giving it a try
