Toothbush vitality

Meet my new toothbrush, the Oral-B CrossAction Vitalizer.
I laughed at it in the drugstore; I’ve never seen such an over-the-top bit of dental maintenance equipment. It’s tricked out with bristles in three colors, set in at four angles and at five heights. It has a fat, rubbery handle like the side of an overpriced gym shoe. There are rows of flexible fingers along the sides to massage your gums.
It even has a demo video.
In a fit of caustic humor (and a need for a new brush) I bought this $3 example of technology and engineering put to frivolous purpose. The joke’s on me, though. It’s an effective toothbrush and I enjoy the gum massaging action of those rubbery fingers.
