[Q]: Cordless unit caused the GFI and trip and not the unit will not charge at all.. Dead.. Nice unit, easy to use takes two tanks with of water to do the job, one for bottom and one for top teeth. NICE UNIT if it was working. I will be contacting the manufacture for the 2 year warranty.
[A]: Update. Unit was replaced by factory. Works great good feedback from Dentist.

[Q]: My book club chose this book for one of our summer reads. The plot description made the book sound like a good read. They were not even close. The basic plot of the sisters trying to understand why their mother murdered their father was okay. But the individual story lines of each sister left much to be desired ( unless you're a fan of graphic sex novels). I did finish the book, but what a waste of time! I had to miss our discussion of the book, but I hear it was pretty lively.
[A]: The plot description made the book sound like a good read
