I've been using Mio Slice for over four months now and it has literally changed the way I train. I connected it to my Samsung Galaxy S5 with no problems. I tested the hate monitor with the chest strap I have and it works correctly. I'm surprised to see so many negative reviews. Basically, there should be problems connecting the device. You can literally use this watch without your phone. My only issue is that you can't see the display in the sun, which is fine with me as I mostly go to the gym in the evenings and run. The odometer works fine although I only use it to measure heart rate. This allows me to stay in the desired heart rate range. I can either slow it down or increase the intensity just by looking at my wrist. Great idea and game changer for me. This motivates you to work even better than you did a week ago. I wish everyone the same positive experiences as I have. Customer service is great if you have any questions. I did not buy this watch here, but directly from the manufacturer. This is an honest review I had to give based on the positive results I've had with Slice over the past four months.
