According to the product specialist

Pros
The screen is clearly readable no matter the circumstances due to the automatically adjusting backlight.
The Hammerhead Karoo connects to the internet via wifi, a mobile hotspot or by connecting to the Companion App.
Know in advance when you're nearing a climb with the special climb function, which provides information about length, gradient and duration.
The clear, extensive Workout Player makes training easier and more efficient.
The Karoo can connect to smart lights, radars, power meters, heart rate monitors, eBikes and even SRAM AXS components.
The large, clear colour display is very easy to read in all light conditions.
Innovative wind sensor for real-time aerodynamic insights and optimal performance.
Advanced navigation with audio turn-by-turn guidance and improved map display.
Intuitive touchscreen controls, physical buttons and synchronisation with the new Wahoo app for your phone.
Cons
The Hammerhead Karoo requires recharging after about 15 hours of use.
The Karoo can be paired with your SRAM AXS group, but not with Shimano Di2.
The large display makes the device less compact than the ELEMNT Bolt or the ELEMNT Roam, for example.
Please note: To mount the Wahoo ELEMNT Ace on your handlebar, you need at least 6.8 cm of clearance between the edge of the handlebar and the centre of the mount (see photo).
