Great Product & Seller is The Bomb!
My 17 year old grandson wanted one for Christmas.  I knew it wouldn't be here on time but ordered it anyway.  He got the one that turns turquoise when it's charged.  Don't be shocked when it's white when it comes.....I'm just a Nana who knows nothing about this stuff.  At first I thought the wrong color was sent until I sat down and read the product description.  It charged up in a flashlight beam in about 5 minutes and the color change is really awesome.  There was a problem because the charge key wasn't shipped with the product.  I contacted Amazon and the seller responded asap to apologize and say they were shipping the key AND a surprise gift because of the problem.  Really appreciated their attitude.  The pendant is nice and the design is well done.  All in all, a good experience.
