I looked at one of these because I sometimes need to leave the dogs in the car for a while and in the sun this can heat up quickly.
Wasn't convinced this would work (and about the price tag) so I did not buy it. I now found a way to let the engine (and with that the A/C) run when the key is removed from the ignition (steering lock engaged) and the car is locked. Press the clutch and the engine stops. Total cost less than 20€ for a relay and a few push buttons and a power diode.
