GELOMUC Breathing therapy device, 1 pcs

Hello! So you can provoke coughing and expectoration of mucus with this Gelo Muc. However, since using this device, I have been getting more and more coughing fits with a real gag reflex, not only when using the device, but also when there is too much strain. This affects the vocal cords. I'm not sure if this is good for me. I have very severe COPD. However, the device does have a cleaning effect. It is also robust. Everyone has to try it for themselves.
