He probably took of the wedding ring for the picture because the product is targeted to young unmarried people. Many married people don't like wearing rings of any kind. They just don't like rings. No biggie.
I looked at that picture again. He has the ring on. And it looks like it may be too big. Perhaps it sometimes slips off and he doesn't want to lose it.
Now we judge a stock on the merits if a guy has his ring on or off?
