IFLYING Wireless Digital Alarm Clock with LCD Backlight Temperature Humidity Display Screen

Worked great initially - not that accurate in terms of internal and external temperature (external being about 5 degrees to high!). The unit is USB powered to it is powered by my PC, with the time supposedly being maintained by a battery. Alas I've given up resetting the time - this resets itself every week or so, even after I've changed the battery! The outside sensor "worked" for a couple of months then following a heavy rainstorm, went intermittent, following rain a few weeks ago packed up. So basically now useless as a clock!

this product is useless the outdoor sensor will not send temperature to the main unit unless it is right next to it.
