Review on Lichamp Small Desk Fan: 7 Inch Metal Frame with Clock 🕒 and Temperature Display - USB Powered Electric Cooling Fan with LED Flashing Display by Tristan Graham

It seemed nice to me. I wish I could read other reviews, I can't leave the fan on overnight. Also, it consistently reads 10-12F at ambient temperature. Started at the right temperature and after a few minutes of operation it's at least 10F. As someone who designs electronics and firmware I'm surprised considering it's a fan, all they had to do was make sure the sensor was connected to the case or air was flowing over it. To turn off the time, add a small capacitor to keep the RTC running for 7 or 10 days. Unfortunately defective, return.
