Have had this bracelet for about a year now and it really has everything I want in an activity band and I'm delighted with features, interfaces and battery life. What draws down the rating is the completely hopeless sync via Bluetooth. Every second training session loses that sync and on and off, I need to go in and sync manually so that the automatic sinking will start. It starts to get really tired and it takes on the good and the experience with the product. Now I'm looking at a new product. Unfortunately, there will not be a bite.
