Review on Wireless Indoor/Outdoor Weather Station With Digital Thermometer, Remote Sensor & Alerts - Protmex PT3378 by Mark Albright

It looks like the pictures and everything works fine, however, the readings are just inaccurate. I placed the remote sensor on the counter next to the main station to test if they would give the same info, and there was a five degree temp difference and 40-60% humidity difference. Also the remote sensor is not very outdoor proof, mine got water in it and corroded the batteries. It still works, I just now keep it indoors in another room. Also compared readings to other high quality thermometers and humidity sensors and neither matched up. The instruction manual was clearly not proof read by an English speaking person, amazes me how common this is. Lastly, as far as I can tell, there is no way to calibrate the barometer to your local elevation, rendering it useless.
