Review: Yes, I know that in a perfect world it would be included with the Kindle HD 8.9.......

But it isn't.  So after reading some comments in the Kindle Forum about the slow charging time of the USB alone, I ordered it with my Kindle.  It does charge quickly (quicker when you remember to turn off the wireless first).  The reason I've given it a four instead of a five rating?  It just seems a little flimsy to me, and it needs a longer cord to enable one to reach an outlet while using and charging.
