BB only had the red Tylt Vu so I decided to wait for another day to get a black one.  They exchanged the puck (essentially giving me a whole new kit even though I told them I only need the puck and they should keep the box and cables) and, for now, this one seems to be OK.  For now.  I spoke the the Samsung rep who said he never heard anything about the charger issue but when that rep was busy with another customer I asked the same question to the second Samsung rep and he said that a few people have already come in to exchange the charger or get something different and that he has heard other reps from other stores tell a similar story.  
Hopefully this one works for me and I can use it for home and overnight charging.  The Tylt Vu will be for work.
