I purchased three of these for my son and daughters from the product's website, ([...]) for a Christmas gift. From the moment we received them, the watch display on both of my daughters stopped working within a day or two. IMO, a defective design that shorts out display battery almost as quickly as you replace them. I consider myself lucky that 1 out of three worked. I have tried repeatedly to contact the company located in CA., but have only gotten voice mail. E-mails worked slightly better but don't count on any customer service from these guys.? Over promise and under deliver must be their motto. Good Idea if it would work as it's supposed too!
Kids love them as a flashlight but they wont wear them now because there is no display.
Replacing batteries cost me more than buying a new watch.
