Advanced version of coziam steering wheel knob (drinking measurement + HOD capacitive touch sensor, etc.)
The coziam Steering Wheel Knob is an auxiliary Steering Wheel Knob designed with the comfort of the driver's handle grip as a top priority. The ergonomic curved design reduces wrist and finger fatigue and is easy to attach and detach, so it can be applied to a wide range of vehicles.
The basic model is a functional Steering Wheel Knob, which can be combined with the advanced version (drinking measurement + HOD) to add smart features. This is particularly useful for people with limited transportation (elderly people, etc.) and increases stability when driving for a long time.
