Excellent value and ease of use.
Execellent quality Hygrometer using to check humidity of 3d printer filiment. Like that you can turn it off so saving battery life when not in use. and easy to use. Functionality is good not only humidity but a temperature moniter as well Not sure of the battery life as only just received them and they were all active on arrival They look good in the cereal box with the fillament making it easy to desplay and read.

Not a bad little room thermometer and humidity sensor.
I bought this pack of 6 room thermometers and use them in pairs to get an average reading. Tested all together they read +/-1°C of each other, with similar variance on the humidity reading. However, for the price, this is totally acceptable. Plus they're discrete left in a room, and clearly show the readings that I want to see.

Finally, a way to know if it’s too humid to print… or just too humid to exist!
After my latest adventure in 3D printing, I stumbled upon the Thlevel 3-Pack Hygrometer Thermometer, and let me just say—these little gadgets have changed my printing game more than my printer ever did! First off, I used these monitors in my Bambu P1S AMS unit, and after printing a 3D model to hold them they fit snugly like they were born for the job. Now I can keep an eye on the humidity while I’m printing, which means no more warping or failed prints due to the great humidity mystery. You know, that thing where you think, “Is it me, or is my filament just dramatically melting into a puddle of despair?” These hygrometers are easy to read—big, bold numbers that scream “LOOK AT ME!” even from across the room. Plus, they come in a three-pack, which means I can have one in the printer, one in the basement, and one in my sons room (for all those moments I wonder if my son is creating a tropical rainforest in there). The best part? They help me monitor the humidity levels in my house, and boy, does it keep me on my toes! If it gets too humid, I can adjust my dehumidifier faster than you can say “failed print.” It’s like having a mini weather station that only cares about my filament’s wellbeing. In summary, if you’re into 3D printing or just want to keep your house from feeling like a sauna, grab these hygrometers. They’re reliable, easy to use, and a must-have for anyone who believes that accurate humidity levels are the secret to life—right up there with pizza and coffee.

Good value
Nice units fit well on tray in 3d printer filament container

Seem to be accurate
These are giving off the same temp reading as my hive so are reasonably accurate. I've bought them to monitor the temperature and humidity in my camper van so will see how that goes. So far so good. They are small though.

Accuracy an issue
Delivery was really quick and although the products seemed accurate at first, I found that the RH reading, when below 20% it would keep jumping between 10 and 20%, and you can’t say which value it truly is..

Good, but not the most accurate.
Good value for money and handy size for putting in areas where you don't want a hydrometer to stand out. Display is pretty clear, yet the build quality isn't the best and the devices aren't of the highest accuracy.

Perfect for 3D filament dryboxes
i bought these to put inside 3d filament storage boxes, so that i could measure the moisture in the box. They work perfectly, and clearly display the humidity and temperature in easy to read black text on the screen, they are incredibly easy to use with no setup needed at all. I will be buying more for sure

De thermometers kwamen toe in bruine enveloppe samen gebundeld zonder aparte verpakking nog bijsluiter of iets dergelijks alle maal reeds in werkende staat ( maw Batterijen reeds gearriveerd) god weet hoe lang deze al actief staan.

Bardzo dobrze spisują się jako mierniki wilgotności w pojemnikach na filamenty drukarki 3D. Bateria wystarcza na bardzo długo.
