## Customer Reviews

### ⭐⭐⭐⭐⭐ Superb… if you want an indoor/outdoor thermometer or i/o thermometer/hygrometer go with ExTech!
*by C***D on January 27, 2014*

I'm a hard-nosed, critical reviewer, but this is one fine unit. Here are just some of the plusses:You can easily see the display, even from across the room.It's accurate and responds well to temperature changes.The min-max works intuitively.Using a wired probe means that you don't have to putter with an outdoor broadcasting unit. It also means that you don't have to keep changing batteries, especially in the outdoor, weather and cold exposed unit as in the wireless indoor-outdoor thermometers.Extech also makes an indoor-outdoor hygrometer-thermometer which is the best in its category, too. (See my review of that one for more information.)Their units are well built, accurate, easy to use, and easy to read. All around 5-star recommended.In case anyone's wondering, I have no connection with the company nor was some unit sent to me for review. After much research and many purchases of other indoor-outdoor devices, I determined theirs to be best suited to our household needs.

### ⭐⭐⭐⭐⭐ Excellent thermometer and a good value
*by T***N on November 18, 2014*

This is a very accurate thermometer, similar to one I bought years ago (different brand) that finally quit. I like the large digits because I can read them across the room. I compared readings from this thermometer to temperatures reported by a nearby monitoring station for the National Weather Service. I checked numerous times throughout the day, on a day when temperatures were rapidly dropping, and this thermometer exactly tracked the reported readings every time I checked. Very impressive! These "wired" thermometers work better than those with remote transmitters and are more reliable. EXTECH seems to make high-quality equipment. In the photo, this unit has a green color. The green part on the unit I got is actually a very dark green that almost looks black -- very attractive. This is a great value, and I highly recommend it.

### ⭐⭐⭐⭐⭐ Great Indoor/outdoor thermometer
*by D***E on October 1, 2022*

I had this exact same unit sitting in my kitchen window for over 20 years. The LCD digits finally started going bad. I like the attached probe that sits outside my north facing window. Great display size that is readable from a distance and a decent side angle. Readings appear to be accurate. 1 aaa battery lasts for a couple years. Was thinking of going wireless but this setup is so simple and I don’t have to worry about protecting a wireless sender from the harsh outdoor winter elements around here.
