Barely used! F45 Lionheart Armband Heartrate Monitor - I purchased this for $95 then got sick and had to have a medical procedure. I think I've worn this 4-5 times, but I LOVED it!!! It lights up with blue/pink/red in line with what you would also see on the screen. It has an on/off feature so the battery lasts WAY longer than the OG band that goes around your torso. It also stays in place, I never had to fidget with it and it doesn't get in the way of any workouts, it was barely noticeable that I was wearing it. I have the box, the manual, the extra armband (never worn), the charger, everything. We're having to move out of state and there isn't an F45 where we're moving to. My loss is your gain!!
