I bought one of these a long time ago. Sadly, the display on these is a bit too dim for my tastes, but, skipping that - Pebble was bought by Fitbit a while back and consequently, you won’t get any kind of official support on these watches. BUT! They will still continue to work since Pebble issued an update.
