I bought this to keep an eye on the room where rest were most of my guitars. Perth is a bit ridiculous when it comes to humidity and we have bone dry summers and then we get wet Antarctic winters. I've been trying to get a clearer sense of the day-to-day swings so I can avoid my guitar is getting damaged or cracked. The screen on this unit is very bright and easy to read the set up to less than a minute and the Bluetooth app connection worked on the first try. The app gives you a chart of humidity and temperature overtime, which is very useful. I can immediately see when the room dries out and whether I need to bring in a humidifier. I checked this against another hygrometer that I own and they both measure within a couple of percent points so I think the accuracy is pretty good. For guitar storage, especially when you have expensive instruments, you really need to be careful about humidity and I've seen some tragic cases of snapped neck in dry conditions.

Not that it really matters, but when I bought this item, it was branded as ThermoPro. Now it's TemPro. It's the same thermometer/hygrometer being sold now as when I bought it. I really like the orange color and brightness of the backlighting, but it only lights up when you touch the white frame. Of course, if it was always lit up the two AAA batteries would not last nearly as long. I put this in my garage because I like to be able to check from within the house, what temperature the garage is so I can decide whether or not I can comfortably work out there. I'm in Texas and the garage gets very hot in the summer. A nice touch is that it also reads humidity on the display and shows a calculated heat index on the app. After installing the ThermoPro app on my phone, connection via Bluetooth was easy. See my second photo for a screenshot of the app display. It shows the Temperature, the Humidity, the Heat Index and a graphic comfort scale so you can tell at a glance the relative comfort of the heat index by color. I didn't notice before purchasing this because I was looking at a dozen other brands, but this one has Humidity at the top of the display in slightly larger numbers than the Temperature, which is at the bottom. Looking at other brands just now, I see that maybe 80% of them have the Temperature at the top. I understand that humidity is very important to people using these in grow tents, but for my garage, temperature is more important, so I'd rather see Temperature at the top and Humidity at the bottom. Maybe it's nit-picky but, out of habit, when I glance at this I always notice the top number and think of Temperature first because my other digital thermometer is set up that way. So, I'm deducting a star for that. Otherwise, it does what it's meant to do and the app works well and shows the Temperature first! (see my middle photo).

This is a PERFECT piece for my greenhouse. The extreme Texas weather always has me freaking out over my greenhouse temperatures. Most of them are temp controlled. I bought 1 of these so I can verify quality through summer and winter. So far in the winter it has been awesome. It’s accurate and reliable. It was easy to set up to my Bluetooth and my phone. If it stays working as good in the summer, I’m the hot greenhouses also, I will definitely be purchasing more for each greenhouse. The price was also very affordable.

I got this to put in our crawlspace to keep an eye on the temperature by our water lines during sub-zero cold snaps. It has been keeping accurate temps when compared to an analog dial outdoor thermometer and the battery life seems great. Saves us from having to open the crawl and stick our heads in there to look at a thermometer. I cannot speak to the accuracy of the hygrometer.

Only thing that could make these better would be wifi compatibility so I can check them when I am not home, or at least if it saved records from when I am home, Vs when I check. Otherwise I got them to monitor the basement and garage for temp and humidity and its great not needing to go down there to read them and have insight. For the price its a wonderful tool! Theres a kick stand to place it on a surface standing up and a magnet in the back which made it easy to mount in there . Id recommend them for sure
