Mine come in the mail yesterday . it will not charge . . therefore will not sync . the blue indicator light remain on for only a few minute -lrb- less than 5 -rrb- and then shut off . turn the switch to on ... there be no light indicate status - not even a blink . I email Cust Serv . and they send instruction for all the step I have already follow . no mention of what the problem might be , from the description of the problem I have send to they . the response be a waste of time . I do not recommend buy one of these unless you can easily return it to a store . need to return malfunctioning merchandise by mail be annoying .
