    Happy with the watch just hope the battery lasts. I've noticed the watch face being used is what makes the length of the battery life. Over all very happy so far.

    I think the only downside is the battery life. I get maybe 2 1/2 days on a full charge.

  • EKG monitoring is horrible

    I love everything about this watch except for the EKG monitor. This is one of the reasons I bought this watch. I have AFIB and wanted to record my episodes. This watch makes it very hard. By the time I go through all of the prompts, my AFIB is over. All of the crap you have to go through, then your success rate of getting the watch to actually read your finger is extremely frustrating.
