Shark Tank Fails?

    Some products, even if funded by Shark Tank, are so astoundingly unnecessary that you'd have to wonder how they ever went into production.     I remember how outraged some people were when it was revealed that Jackie Kennedy had a towel warmer installed in a White House bathroom.  Now I see, via online garage sales, that people are selling their never-or-little-used Wipe Warmers.  Alert CPS:  somewhere somebody is using room temperature diaper wipes on their child.
