Lung Breathing Exerciser, Core Strengthening Exercising by Opening Airways and Improving or Restoring Capacity

Ive developed asthma in my middle years to the point where Im wheezing without exercise and having a tickly cough producing tiny amounts of phlegm and Ive heard of people using these kind of aspirators to help build their lung capacity.It seems expensive for what it is, but comparable to similar products, so I thought I would try it for a month and see how I got on.Initially, I couldnt work out the correct way to use it, but realised soon afterwards that I was holding it pointing to the floor too much - when checking the sellers description, I noted that it was supposed to be parallel to the floor. The instruction leaflet isn't extremely informative, but I did work out that you can tilt it at different angles to make it easier or more difficult and hopefully, it will help you remove any mucus in your airways/on your lungs that causes your respitory problems.Easy to clean, pocket sized, so can be taken anywhere
