We were out shopping yesterday and while it might not be the perfect gift for the wife it is a good gift for anyone on your list who cares about their health and will spend a lot of money and time worrying about it.
Kohls has a UV-C light sanitizer that will kill staph infections and other bacteria, like the ones on your phones ,computers,cutting boards used for cooking and so on.I have seen them used in foreign countries to kill bacteria in water.
They are normally $40 and are now on sale for $20. So if you happen to have a Kohls in your area it's a good deal. If not the company that sells them can be found at
www.markfeldstein.com
they can probably direct you to a place that has them near you.
If your wife is a germophobe she would love you for it !!
