77 % OF THE REVIEWS SAYS IT ALL !I bought the product for three devices, but did not work on two of them.Many phone calls with people round the world in training and could not even speak or understand my English did not help.My e mails were not answered.If you want to cancel you have to spend a fortune ringing as they do NOT allow you to cancel online .I am going to use a more customer consumer concerned company than this one! UTTERLY USELESS COMPANY ....
