lightweight easy to use
Tend to be unsure of medical devices and their efficacy, didnt know of any medical professional who had any experience of using the device.
Found instructions easy to follow and it appears to be having a positive effect. Being used three times a day. Still tend to be breathless on occasion but chest feels less congested and expectorant significantly reduced. Only been using it for 2-3 weeks up to now.
