Product review (5 stars): Helps handle the environment
Perfect!  I didn't believe the thermostat on the wall and I was right!  The thermostat was wrong.  Also, I can move it from room to room to see where all the heat/ac is going as it is different in each room, and it gives me a chance to change the vents and even things out.  Also, if you are like me, I am sensitive to high heat and humidity, this little gadget helps me decide when it's best to be inside or outside.  It is small enough to carry around, but has numbers large enough for me to see even at a distance.  I think you will like this product. I do!
