It works!  I was skeptical about ordering it because the ratings weren't great, but short of buying a new Nook or replacing it with a Kindle,  it was the best short-term option.  The original plug-in part made a sizzling sound one night and stopped working.  My husband tried to plug the USB end into one of about 20 USB to plug-in wall chargers that we have around the house and none of them worked.  We're assuming there must be some proprietary thing with the Nook USB end that won't let you use generic wall chargers which really sucked because he couldn't use his Nook for weeks.  If you are contemplating purchasing a Nook,  it may be something to take into consideration.
