I feel no resistance at all on the exhale/inhale....is it working?
The Breather requires a certain amount of pressure to engage the silicone diaphragm.
So, if you hear it engaged you have provided the pressure required to perform at that setting.
If you are not feeling resistance at all, the diaphragm has not engaged and you will not feel the resistance. This was a safety protocol that was put in place. If you do not produce the pressure required for that resistance setting the diaphragm will not engage. All of our Breather devices have it. It is more prevalent in the Voice and Fit because of the amount of resistance that will be applied at the higher settings.
