Full disclosure here, not blaming the watch/technology. Just looking for unbiased opinions, right now I am obviously grabbing any excuse to justify/keep the watch.
I have to position the watch on a certain spot between some ink that has clear skin. Most of the day I seem to be fine. However, it is those times when I find myself throwing laundry in and out of washer/dryer and other acts that can (not always) reposition the watch I will notice the HR sensor lose connection. For exercising I use a Polar H10 so not too concerned there. Also, I noticed if I am doing anything like raking my lawn, or just in and out of my shed moving *** around, I can find that it repositioned and lost the HR. I am an engineer so I spent a lot of my time in my office with my ass planted on a seat outside of my workout schedule, so most of the time all this is a non issue. It is the weekends or evenings when I flip the switch with work and start doing those things around the house I will need to keep an eye on the watch. Seriously considering laser treatment on a small area of my wrist.
Would a little aggravation a couple times a day at times and a quick re-adjustment be a non-issue to you?
