Connected to aux in the car radio, everything works. The sound quality is excellent. The sound is loud. In addition, i ordered the voltage stabilizer board 1,25-5 v (step adjustment) from this seller. Soldered the microphone and got hands free in the car. Nothing is heated on the fee.

The items arrived after 13 days which is 15 days early!Manufacturing quality looks perfect. The item works flawlessly as described. Pressing the set button lets you change the set temp to where you want the relay to switch. It does siwtch the relay between 0-2° prior to hitting the set temp and switches off 2° below set temp. (E.g. set temp 35°C -> relay on and off at 33° or 35° respectively)When relay off it needs 19.7mA at 12.0V and when relay is pulled 69mA. (Which is: ON: 0.83 watts; OFF: 0.23 watts).The seonsor is very sensible and measures temps accurately in very similar to other thermometers and the display is clearly readable.I will surely buy more units as they are working great and are cheap.
