Review on 🚗 Yosoo 12V Car Digital Thermometer Voltmeter Clock Alarm Monitor - Multifunctional Auto Meter with Clock, Voltage, Temperature and Battery Monitoring - Green LED Display by Michael Syph

Watch works well, time/date is accurate. Temperatures are a different story. Since it needs to be in the car, most of us would have it on the dash. This will not work as the sun heats up the device and greatly lowers the internal temperature! The outdoor sensor has such a short cable that it can hardly be pulled out of the car. Therefore, the heating of the body by the sun or the engine also reduces this temperature. The last downside I see is the alarm. You can install it and it works fine. However, if you press any of the top buttons other than Snooze, the alarm will turn off. The snooze button is in the middle of the 5 buttons and they are all the same size. It's pretty hard to make sure you just hit the snooze button.
