The ventilation heater fan arrived very late due to DHL handling.
Not tried yet, but looks worth it for the small amount of money.

So far it works okay it heats up normal not much warmer in the car but helps defrost the windows

Good product and you can use it for so long because it draws power from the car, the plug you can use over time with prolonged use.

The idea is good. immediately warm air. until the car can produce warm air. but what I didn't like was security. So after 5 minutes the cable gets warm up to 44°C, the plug itself up to 70°C.
2 switches, first for heat and second only for fan
150 w. Air becomes warm up to 50°C.

Overall, almost as described and it does heat up as much as I would like because warm air flows andit's noticeable.

Everything is fine.

The front grille was damaged during transport but still worked.

Good fan
Could be a bit quieter, airflow is also rather low.
Could have more performance
This toy acts as a real supplementary heater.
