@christelvg Have not had mine long and I cannot testify to inaccuracy. You have to manually put in weight and reps before lifting under strength trainer and start activity for other activities if you want better results. I wear on non dominate left arm about 1-2 inches above my wrist. It has not gotten in the way nor has it bothered me sleeping. On days my recovery is low it seems accurate bc those days I am feeling worn down. The most inaccuracy I did see was a day I literally rested all day did nothing and my strain was a 15! All I can think is doing house chores, gardening, and not doing any physically exertion stressed me out which put extra strain on me. Who knows? I do like it keeps track of the days when I ruck and my routes so if I want to do a long ruck I can look it up and remember to follow that path. The battery seems to last long and charge quickly.
@christelvg I love mine. I wear it on my dominant wrist as I am a nice mechanical watch guy on my left wrist. I’ve enjoyed the heart rate monitoring and other data. It sits a bit higher on my arm than right at the wrist, so I can still wear grips on the rig. Haven’t tried wrist wraps over it but would imagine that would not be very comfortable.
A con, I’ve found that I need to manually start my activity to get the best results vs auto-detect.
