Very disappointed

Bought ring 2 from Amazon, installed it and put packaging in bin after it took 5 days to fully charge. Worked ok for a few days and lost charge…i have it on the minimum of settings…had to charge it again and it showed no charging light…it went to 91% after about 30 mins of charging then wouldn’t charge any more and I’ve just set it up again with the same problems and new ones which might be the app…really disappointing
