Terribly inaccurate – Garmin Connect™ Review

One example: I slept at 11:50 and got up at 8:10. When I took a look, it said from 11:56 to 6:27. Ok. 11:56 is close to 11:50. So I updated the 6:27 to 8:10. Then it said manual data entry and totally ignored the time of deep sleep and light sleep data that were recorded before. It is just terribly inaccurate. Cannot trust the data there.
