Easy to use, Accurate, Peace of Mind
Great Hygrometer, great way to measure temperature and humidity in a given room of the house. We use it to monitor our baby’s room to make sure the temp and humidity is at a level where he’ll sleep well. We’ve noticed if temp is too high or humidity is too low he doesn’t sleep, so this helps us ensure he’ll have a good night sleep. We use it for the rooms that are farther away from the furnace / AC to help us know if we have to adjust anything. We’ve had both units for several years. I’ve used it in the freezer, fridge and it seemed to perform well in both environments. It’s super easy to use. Definitely recommend!!

Accurate, easy to read, and very useful
This is a great little thermometer and hygrometer. The display is clear and easy to read at a glance, and it updates quickly when temperature or humidity changes. I use it to monitor indoor comfort levels and it’s been very helpful, especially for keeping humidity in check. Setup was simple, battery life has been solid so far, and it feels accurate when compared to other devices in my home. Small, reliable, and does exactly what it’s supposed to do.

Accurate and useful, But....
I have purchased these 3x. They use 1 AAA battery that lasts over a year. They work well indoors, outdoors (NOT in the rain), in a fridge, freezer & in bathrooms. the ONLY problem is the LCD goes bad after a year or so and the numbers start to disappear. For $10 each, one would expect them to work longer. On the other hand, the magnet on the back is VERY STRONG and they bond to ANY metal surface.

Easy read
This has been very accurate for me. It’s one of the highest rated brands in my research. Easy to use and read and the speed of accuracy has done well for me. I like that it reads both temperature and humidity. Great quality.

Amazing.
I ordered because my parents had these same ones and because I’ve been running my cool most humidifier because it’s been pretty cold in Florida. Works great. I love how it shows the temperature, humidity level then shows what is too low or too high for readings.

Great quality for monitoring humidity
Works perfectly. I tested it in several different rooms and was delighted to see it match another item I had. Very excited to use this to monitor the humidity of my room during the winter to prevent sickness.

A very nice and beautiful product. As for accuracy I kept it outside my house and compared to the values of local reported weather. Temperature was almost completely accurate. Even humidity it reported was very close. It clocked 73% when weather reports said 80%. I use this instrument to decide when to switch on the humidifier at my home.

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.

Funciona correctamente, con mediciones muy exactas. Pequeño, pero con una visión de los dígitos muy clara. Trae un soporte trasero para colocarlo de pie sobre alguna superficie, y también trae un imán en la parte trasera para pegar a una superficie metálica. Opción de lectura de la temperatura en grados Celsius o Fahrenheit, se puede cambiar a través un botón también la parte trasera.
