Query: DO NOT BUY!!!

I purchased this product and had major problems with it. It does not work with a mac and only after several attempts did it work with windows, or so I thought. When I came back to my computer to load the pictures, it stopped working. The key chain would not pull up the options menu. It would only turn on and whenever anything was pressed it would turn off. Don't get this product, it is defective and will only make you frustrated and upset that you purchased it.
