Review on ORIA Indoor Outdoor Thermometer With 3 Wireless Sensors Kitchen & Dining by Scott Carlile

I've been using these to take measurements in the attic for a few weeks now. Works perfectly! Setup was easy. The only criticism I have is that the sensors are slow to reflect the current temperature when first placed in a location where the temperature is different than before. It takes at least 30 minutes to set the current temperature. This is normal for me as I leave them in the same place for a long time. But if you wanted to walk around with one to check readings in, say, different rooms, that would take a long time.
