Samsung has lost a loyal customer. Samsung watch is inherently defective. Sensor cover fails resulting in moisture intrusion - allegedly voiding warranty. Samsung uses asinine warranty language to escape liability for marketing/selling watch with known design/manufacturing defect(s) which render it unfit for its intended purpose. If (when) watch fails, Samsung will likely charge $350+ to "repair" the watch (i.e. return it to its poor quality condition). This is a known issue. I would NOT BUY THIS WATCH again. Unfortunately, this experience prompts me to switch my phone/watch from Samsung.
