I purchased it due to a nasty attack of bronchitis leaving my chest full of nastiness. The box contains the device itself plus three metal balls of different sizes. The instructions were clear and simple so I began with the smallest ball. It was good, and I could feel the vibrations but it wasn’t enough, the middle size one was better but, in true goldilocks fashion the last was perfect. I could feel the vibrations right to the bottom of my lungs and after completing the recommended 10 repetitions I had a coughing fit that left me feeling clearer than I had been in days. Make sure you have tissue or whatever nearby for when you cough out the secretions. It is very simple to use. It’s robust, made of nice strong plastic in a pleasing shade of blue. It disassembles quickly for cleaning and reassembles easily too. It’s compact enough to store without being annoying. I’ll be recommending it to people. Review: Highly effective, inexpensive, great little gizmo. - This is a fantastic oscillating lung exerciser that is sooo much easier to use than the Airphysio - and at a fifth of the price. No faffing about trying to find an elusive 'sweet spot' to get the darn ball oscillating, and robust in its twist-off, perforated cap, so I won't have to reinforce the mechanism that closes it with epoxy resin to stop it falling apart. I've been using the Airphysio device for months and whilst it effected an improvement, I still find it infuriating to get into the exact position, with the pipe thing at exactly the right angle and with exactly the right pressure of exhalation for the darn ball to oscillate. This Opep device worked immediately, no faff, obvious oscillation, so much so that with the same weight ball as the other thing, I got light headed and needed to adjust it. This is worth it. It says it should last 6 months but it looks and feels far more robust than the very expensive version, that cracked and broke within a few weeks. Highly recommended. ## Features - Clear Mucus Naturally - Phlegm builds up and causes a cough, which in turn makes you very miserable,Mill.STEPS DEVICE for mobilizing stubborn mucus in airways,Improve your wellness and breathe easy again. - Build Stronger Lung - The device exercises lung muscles and increases lung capacity.
