*by A***A on Reviewed in the United States on December 23, 2015*

I purchased this in November and the unit was DOA. My original review was 1 star and I leave it at that. Construction appeared solid but the were no real directions on how to switch modes/use the item (if it had worked).  I upgraded the overall review to 3 Stars because Shenzhen has a good Customer Service department and promptly issued a refund.
