Generally Happy
Im a cell customer, so cant comment on the Bluetooth - though I did look at it and seemed easy enough to add Bluetooth control so not sure where the complaints are from.
Ultimately I can start my car and unlock it from my phone and watch. This is pretty convenient, when you remember.
Not so useful last minute. If love to see:
(1) 3D touch enabled for start, lock, and unlock.
(2) Geo fencing features
(3) Presets (eg to warm car at points in day)
(4) IFTTT integration.
