Nascool Breathing Exercise Device for Lungs, Inspiratory Respiratory Muscle Trainer for Athletes, Lung Exerciser Device for Adults, Children, Swimmers, Smokers

This product will help me breathe easier and make my long is more efficient as they are exercised. And shopping for this product on Amazon with free shipping was added benefit and surprisingly less expensive than going to a Health Products dealer.

Very effective at decreasing my back pain. Easy to adjust. Messy. Saliva builds up and can pour out of the unit. Inexpensive.

I have breathing issues due to a nerve injury.. this really makes you strain to inhale, which is good when trying to “strengthen “ your Lungs. Overall I like it..Side note: WEIRDLY, I also recently have gotten Panic attacks (due to injury) and I grab this and it helps (it’s calming.. very odd, probably just me…😂)Worth mentioning though ✌🏻

I used the product as directed, however a month after buying it, the device broke. I can’t open the device but the exhale valve seems to have failed and is stuck on a much harder setting. Would not recommend.

I have been noticing that I get short of breath doing minor activity. The stairs especially, and our home is 3 floors. I've had all tests and they showed nothing was wrong. I bought this in hopes of expanding my ability to take in and release more air. It worked for a week or so then fell apart. I should have spent a little more money on a better quality.
