I'm reading a ton of comments from Fitbit Sense users who are finding that their Fitbit Sense HR monitor is way off. I too am having that same issue. When I'm in any exercise mode the heart rate reading will sporadically go from 140's-150's to the 120's in fat burn zone. This happens all the time. I've done all the troubleshooting but to no avail. I moved it to all different levels up my arm, worn it tighter, looser. I've even worn a wrist band over it to try to get it to stay consistent. Nothing works. I'll be in the middle of an intense workout and it'll buzz and say I'm in fat burn zone. I'll have to stop and try and wiggle it around and adjust it, wipe the back and put it back on. It'll work again for about a minute or 2. I feel like I have to keep interrupting my workouts to keep an eye on it. It's ridiculous. Why hasn't fitbit addressed this? I'm wondering when there will be an update to fix this. It sounds like so many people are dealing with this. Why would they put a product out without testing it and tweaking it to make sure it's perfect for the consumer. It's so frustrating!
