ThermoPro Indoor Outdoor Thermometer Wireless, 500 ft Outside Thermometer with Cold-Resistant Sensor, Outdoor Thermometers for Patio Waterproof with 3.3" LCD Display, Backlit Outdoor Temperature Gauge

I was surprised how good this unit is after a month's use. The only feature I'm not sure of yet and which could affect future review is battery life, but so far it is much better than the Oregon Science unit it has replaced in that:• the sensor transmits easily from outside one end of the house to the room completely at the other end and through metal siding; the last unit could not do that• While initially I had the sensor indoors right next to the receiving unit and the indoor and outdoor temps differed by a few degrees, I found this was from handling the sensor. The difference went away with time. Outdoors, the sensor sends a temperature which is within one half degree of my expensive and accurate Davis Vantage View weather station. The two devices are in someone different places in the yard, one in sun the other not, but on cloudy, calm days when the readings should be the same, they are• The contrast on the display makes it very easy to read. The display unit is relatively small but the digits completely fill the whole screen and are readable from across the room• The backlight works very well with a tap in the center top of the display• The max-min feature is not explained well in the manual but works this way: you reset the max-min by holding that button for 5 seconds, then there is another button that gives you the choice of showing the max-min temps from the last time you did a reset or the max-min temps within 24 hours of that reset. So if you reset at 11:58 PM and use the 24 hour choice it gives you the max-min since the last 11:58 PM and then starts all over for the next 11:58 PM. It counts 24 hours internally. There is no clock. If you choose the “all time” setting instead of 24 hours, the max-min never resets and you will see the max-min since the last time you reset which could have been a month ago. The unit only operates in one of the max-min modes at a time. If you set it to "all time" you cannot display the 24 hour value.• The only”con” I would register is that there is no beep or other indication that the max-min reset has been successful. You can check to see if the max-min are both the current temp when you do the reset, but a beep would be nice.

Accurate, reliable and very useful

It is easy to set up and the transmitters work very well. The IN readout is dedicated to reading the temp and humidity of the room I keep it in. The OUT readout can handle up to 3 sending units. I keep one unit in a shady area of my deck out back. I got a second sending unit to monitor the temp in my unheated garage. They all work but I don’t know how accurate the transmitters are I still have an older LaCrosse unit that differs by .5 to 1 degree F inside but about 2 degrees outside even though the sending units are close together. This unit’s OUT read is closer to the temp on my weather app so that is good.

So far this unit has worked great for my use. If it's off by a degree or so, who cares? I need to know if it's 60 or 75 degrees outside so I can dress accordingly BEFORE I go out. I've owned another one of these for several years now and it's still going strong. When it's 20 to -10 during the winter you do need to change the outdoor batteries more often. Cold with kill batteries sooner.
