For quick cleaning, the shaker can quickly and easily dismantle. This is very important because when blowing up all sorts of moist air that condenses and remains in the unit collects. So best disassemble and clean daily. Hot water is sufficient. The material of the shaker is lightweight and seems to be tough. You do not chew on the mouthpiece. This is also ohen bite marks very well.
The application is well explained on a INSERTS and after a few minutes exercise that works well. You can feel the vibration in the lungs. By raising and lowering the Shakers during exhalation can affect the resistance of the ball. I use the device in the evening watching television and in between when it arises. Up to five times a day the Shaker is used by me. The former effect is itself very well for me. Less Schmoder is present in the bronchi, I can do better expectorate. This I also need less aerosol. The bronchial tubes relax by the vibrations and I can breathe better. Also, I breathe in deeply, since I use the shaker. I breathe otherwise too shallow.
My Conclusion:
The Shaker is a great Therpiegerät. After a week I breathe much better through, using 50% less aerosols and feel better breathing. Although the price of some plastic and a ball is quite high, so is the idea for the device alone already worth the price. I have procured better quality of life with the Shaker.
