I’ve now had this watch for three months. I’ve worn it every single day. I’m truly amazed by its capabilities. It links with my continuous glucose monitor through my iPhone and shows my blood sugar on the face of the watch. It has motivated me to lose 10 pounds in three months just by meeting my move goals every day (walking more and taking the stairs, not a new exercise regimen). I love the technology of the watch. My daily resting heart rate has significantly improved. As a health tool, I could not ask for more. My ONLY complaint is the short battery life...only lasts about 16-18 hours for me. I charge it every night. Even though it doesn’t have cellular, I can text and answer calls as long as my phone is close.
