I am caring for my Mum who has lung cancer and is due to have surgery soon. Her breathing and lung function is v bad which has led to the operation being cancelled. She wants to buy a device called 'Breathe Easy' by Aerosure. Does anyone know anything about this and more importantly, whether it is any good? It's £149 so I don't want her to get it if it's yet another gadget that will end up in the back of the drawer.
Any advice would be greatly appreciated.
