The Charge 5 has not worked well since purchase. HR does not seem at all accurate ( sometimes under and some over). Since yesterday (Feb.6) it only stays synched for a few minutes then crashes and only shows a partial display. Have tried restarts, removing and re-installing , both multiple times. Today it won’t even send a code to allow set up or if it does it doesn't work and says the process is aborted and try again after another restart. Useless waste of time and money
