Review: Exercise device for lungs - I was sceptical about using this device, but it’s a good little piece of kit. Nothing big and fancy, not bulky, just a small lightweight compact breathing exerciser which promotes health benefits. It’s very comfortable to use, comes with three silver balls and you adjust the amount of balls to use depending on your chest strength then blow. It’s good to use on a regular basis and works well.
Review: Compact and very effective for clearing lungs. - Very effective. 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.
