Hi NorCalDM,
I hear ya! And that includes my post. However, (you knew there was a "but" coming) most of the bromides mentioned above work well. I have used quite a few different de-foggers. Toothpaste even works well and makes your mask smell minty fresh.
Chilly in Canada has a good point. I would not waste my money when I have a suitcase full of potential defoggers. Including a sinus full of snot.

All good info I agree but it does not answer the question the OP asked. They asked for opinions about a specific product that they have already purchased why not answer the question and give input on what you use. I see to many threads on SB that take a turn at the start of the thread and never get back to the original point of the thread "including this post". I wonder how many that have responded to this thread have used the product that was asked about I have and as I said earlier it didn't work for me. Also I didn't waste my money it was given to me to try just had a foggy dive!
