It’s a Chinese product (no point for this guess)
• Nice product for the price.
• Good side table clock if you don’t have any.
• 4 sides do have diff function.
• There is no backlight. Its only 2 LED at 2 corners which blinks for certain time (I guess 30 sec) once you rotate it.
• The settings are lost once you remove batteries (when you want to change battery then have to set the time etc again).
• The temperature doesn’t have decimal which is possible to have.
