Bests & Worsts Reviews from Amazon

I waited about a week before I wrote this review just to see how it worked and the accuracy of the units. I ordered one extra transmitter to keep a track of the temperature in my garage, since the garage faces north and is always cold. I also needed to know what the humidity is in it and also during the summers, how warm it gets in there since I keep my home-canned goods and other staples in my "garage pantry". I also needed to know the outside temperature and humidity measured on the north side of the house. We have another sensor that gives us the temperature, wind speed, humidity, etc. on the southwest side of the house. Now, back to these units, it took them between 3-4 minutes to "settle down" and give me a true reading. Of course, reading all the other reviews, I paid close attention to what others said, and I was patient. I compared the ThermoPro units to the one we have existing in the house, my WeatherBug App on my phone, and the TV broadcast, amazingly, all of the readings on these three units were identical. The TV broadcast was way off. Even NOAH was the same as these three units. (I just wish I was getting the salaries the TV personalities get to make "educated guesses" and be wrong 50% of the time (lol).) Back to the units, the transmitter that comes with the receiver does not have screws on the back to install/change the batteries, reset or manual transmit. It just has a cover, which fits quite snugly. The additional transmitter does have the two tiny screws at the back for the battery compartment. If you change the batteries atop a paper towel, the chances are slim you will lose the screws. And just in case you do, you can either purchase new ones or, as a quick fix, you can use some scotch tape to secure the back. Problem solved. I did take up the suggestion of another reviewer to use Velcro to attach the transmitter(s) to the walls so that they will be mobile. Loved the idea. Installed my two transmitters with Velcro and am very, very happy where I placed them. The receiver is on my vanity so that it is easy to check the outside and inside temperatures while getting dressed. The readout is easy to see having large numbers. The background light is exactly as picture, but I don't need it since I'm asleep at night or have the light on in the morning. I do have the readouts in the scroll position and that is a terrific feature if you have more than one transmitter. This little unit has the capacity for three transmitters, but because I have two, the third channel has blank lines (obviously) and this gives my husband and myself, the visual to know that after the blank lines appear, channel 1 is the next readout (outside temperature) and channel 2 is the garage readout. Simple to install, immensely accurate and totally affordable. I totally recommend this product.
