Bests & Worsts Reviews from Amazon

I have been buying Vicks warm steam vaporizers for close to 20 years and in the past I have only needed to buy one each year--we have very hard water and our water softener adds salt to our water (not enough to taste, but enough to corrode the steam mechanism by the end of a winter season of daily use). I have bought most through Amazon. several years ago, Vicks changed the type of metal used in the vaporizer to something that corroded very quickly, turning the water in the plastic water container a dark grey and shedding bits of blackened metal. I have done everything to try to avoid this (taking the vaporizer out when not in use, cleaning it in vinegar, etc.); last year I bought 3 vaporizers to make it through the winter and it looks like I will end up buying 3 again this winter. The worse part of this is that the vapor that comes out carries the metal particles. How do I know? I put it one a marble table in the corner of my living room and the marble has a dusting of black beneath the plume of steam that comes out of the vaporizer. I just read the reviews for a sunbeam vaporizer that has "stainless steel rods." I think that it is time to try their vaporizer!
