Everything worked so far. Bluetooth, alarm, pedometer. I haven't tried using it as a remote for the camera on my phone. I like it.
I set it for 12 hr time n its keeps going to 24 hr time
Bought as a gift. They loved it, and it looks great.
Nothing Fancy for the price. Easy to use interface with ios12.3.1. Download the READfit app, connect and fill data. Basically pedometer, calorie count and distance. Photo shutter and push notifications for mostly all apps, whatsapp, facebook, etc. Back light too dim. For all the negative reviews, READ THE INSTRUCTIONS.
