I like the concept of the watch and it has a few good points, it tracks my steps, has the weather, heart rate, and oxygen tracker. now what I do not like is that the battery lasts around 24 hours and takes about 2 hours to charge from 30%, the sleep tracker is off (was awake at 4:30am watch showed I woke up at 7am I had already been at work for an hour), I can not get all my contacts to sync, no way to use the quick reply texts, not all texts come through and the instructions are very basic and no user guide. but for the price I paid I can't be too upset but definitely not worth full price.
