My Sense will often continue to read a heart rate long after it is removed and placed back side down on a surface. It also does not read my heart rate accurately. I have a health condition and need to keep my HR below a certain number. The Sense will often tell me I am above that number and when I check my HR using a pulse ox finger monitor my HR is up to 20 BPM less than what the Sense says. At this point the Sense is useless to me and that is quite disappointing considering how expensive it is.
