– Lung Trainer with Adjustable Resistance Breathing Exerciser & Lung Cleanse Device for Enhanced Lung Capacity, Fitness & Respiratory Health – Includes Free eBook (Black)

A nice item, quite robust for it being plastic, it works well. Very easy to clean, and easy to use.

Good to train with

As described - packaged well simple instructions and works for those wanting to improve lungs

Great value for money and son Loved this project after seeing similar on tik tok. Easy to clean

I bought this to improve my cardio, so far it's been working out well the rubber mouth peace is soft and comfy. Turning the the valve at the end increases and decreases the airflow.

Friends swear by this - if you have a bad gag reflex then maybe not for you.

Really gutted as I had heard good things about this product, however mine arrived with the mouth guard off and now it will not seal and the resistance doesn’t change anything. A lot of money for something that’s broken, I have tried to find some way to contact the company but no details

Only used a couple of times. Dont like it

Funktioniert gut, tut was es soll

I haven't used it much but when I used it few times I felt after few weeks better lung like I could hold my air longer

Ist soweit okay
