Detailed Test Results

Overall this model was very easy to use, not accurate for counting steps, and very good at measuring heart-rate accuracy. With recent version iPhones, our experts found it somewhat difficult to pair, very easy to interact with, and likewise for recent version Android phones, somewhat difficult to pair, very easy to attach to the body, and very easy to recharge the battery. In our water immersion test it passed the manufacturer's claim of 164 feet for 10 minutes.
