Battery Life
The Just Corseca Ray Kanabis has a uniquely rugged design, and is also IP68-rated for dust and water resistance. The smartwatch has a built-in Bluetooth speakerphone system with a speaker and microphone, which can be paired with a smartphone just like a Bluetooth speaker, and used for calls.
Fitness tracking on the Just Corseca Ray Kanabis is a bit iffy, but the device has a good screen and works well to view notifications from your paired smartphone. That said, competition products offer better value-for-money.
