I've had one of these for about 14 months. It's been pretty solid for the 13 months, then suddenly the battery keeps dropping charge very quickly, almost overnight. I was lasting 5 days (without a run) and now it's maybe lasting 36 hours. In a world where sustainability matters and products should be towed in the bin, this is very disappointing.
