Company is useless, watches are a waste of money, don't work well and nothing you can do about it. $279 down the drain on a Vivioactive 4S bought in August. You also can't review their products on their website. I guess that should have been a red flag, but I messed up and listened to reviews from magazines and other websites. Do not buy anything from them. Since you won't accept a PDF of my invoice I can't attach it below.
