Fitbit - Worst brand ever!!!

Worst experience I have ever had with Fitbit. I have taken a step to care for my health and as a Discovery member I get more benefits when I use a heart rate monitor device during my workouts. If the device is bought through Totalsports or Sportsmanwarehouse I qualify for monthly cashback on the purchased device should I meet my weekly goals. I bought a Fitbit Versa Lite in April 2019 and after 5 months it had problems charging and I took the device back and was given an opportunity to replace it. I lost a week of my work outs due to this. In December, the Fitbit Charge 3 that I bought in September 2019 started malfunctioning and would finish a full battery in less than 30 minutes. Again I am without a device as the Charge 3 was taken for inspection on Friday. 6 December. In In 9 months I have used 2 different Fitbit devices and both have been problematic. As it is now I do not want to even see the word Fitbit as I get irritated. What a waste of my money, time and energy.
