I have been a very satisfied RADIUS user for more than 20 years and I thought you might enjoy this story:
I was in Whole Foods a while ago to buy a new RADIUS and Steven Tyler (Aerosmith) was shopping there with a friend. They were looking at the RADIUS toothbrushes and Steven Tyler picked up (and later purchased) one and his friend remarked that it was a BIG toothbrush. Tyler replied, "And, I have a BIG mouth."
After some sleuthing, we now hear that Steven Tyler is a big fan of the yellow SCUBA.
