For anyone thinking of getting one of these I must say they are brilliant,whenever I had been in the loft cleaning out etc I would aways end up coughing, and at nite as I lay in bed my chest would be making one hell of a noise,since I bought mine at Blackpool no coughing chest fine couldnt recommend them enough,mine is the dazer one but I would think the other make is just the same.For anyone who as the same problems as I had I would say get one I noticed the difference the first day I put it on.
