This little gadget is simple to use and actually does the job it sets out to do. I noticed immediate relief after the first use, and following that the benefits continued to accrue. The only thing is that once my sinuses were clear and comfortable, I then forgot to use it and experienced a return to my old sinus discomfort. This is, of course, not the fault of the product but a function of a particular character flaw I have. Maintenance tends to be a weak area for me. Overall, I would recommend this product. Considering the numbers of airborne environmental challenges we are all exposed to, I would recommend it to everyone.
