I like this product.
A friend gave me a box of these and I have been using them while I have a sinus infection.  I think the mentholated vapors are soothing and relaxing.  The tablet works with the steam in your shower to create vapors which are a lot like vapor-rub.  I agree with other reviews that say there is a slight "medicine smell".  I don't seem mind to mind that though; after all, I am sick and looking for a little bit of relief -- I'm not looking for a spa experience. The "grit" left over from the tablet washes down the drain easily. Overall I think this is a really nice product.
