Looks good but failed to deliver
20 June 2018
Ongoing bluetooth problems on iOS and android. Looks great but is unreliable with syncing data. Does not hold data, For example, sleep tracking will show on the watch but after syncing via bluetooth the app will tell you no data found for that date! This is after a successful sync. Most times it failed to sync at all.Tried the update app software, no improvement. Tried different phones, no improvement. Tried deleting and reinstalling over a period of 2 weeks. No improvement. Very disappointed as the watch is beautiful to look and feels good but sadly did nothing other than tell the time and the "smart" functionality did not work as described. Returned to amazon for the above reasons.
