Had a surge for 1yr. Was told that the GATT aerver was coming for Windows Phone users to get text/ notifications. Now with the "NEW" Blaze out you'd think it would. It does not. I have a blaze and I do not get text/call/calender notifications and PLUS as a bonus I cannot use my phone GPS to rack my routes. I sell Fitbit, Garmin, Polar and Jawbone yet looks like I'm going with a Microsoft Band 2.
