Query: Just Another "Money Grabber"

I think all of these "magic" products are a waste of money. Most nail fungus just don't go away or if so, it's on their own. Save your money. Recent consumer tip: "Try a diluted vinegar soak or rub some VICKS on your toes". I will give these ideas a try. Probably will need a few weeks to see any effect, but you will still have money in your pocket.
