I've had my Wahoo Tickr since 2016 when my Garmin HRM died. Except for batteries dying, I've never had an issue with it. I did replace the strap because, through my negligence, it somehow got torn. My wife has had two Tickr's during the same period of time. My HRM is used 6 days a week for about 3-4 hours/day, on average. If you take the time to take care of them, they will last you for quite a while.
