I bought this product to help clear nasal congestion I suffer from when I have a bad cold and to help with clearing mucus from my lungs which is a problem because of asthma. The soothing vapours produced do seem to help clear my nose and chest so I consider it to be a worthwhile purchase.
This product was recommended by a locum GP at a time when I was prescribed with a strong antibiotic for an ongoing lung infection. I duly ordered the product and used it according to the instructions hoping for some easing of my breathing problems. However, I have to report it was of no benefit to me and I found the menthol sachets supplied were obnoxious. The product was not expensive and worked as described so not much lost financially. Often you need to try things to see if they are helpful and on this occasion that was not the case.
Very easy to use and adds much relief to sinuses and breathing.
