Digital Humidity Meter Indoor Hygrometer Thermometer,3 Pack Room Thermometer with Temperature and Humidity Monitor for Home, Baby Room,Bedroom,Office, Greenhouse, Apartments (Black)

I'm happy with these hygrometers. They are a little small, as you can in the attached picture, which has a different brand behind them. But the dimensions in the description are accurate, and they are easy to read. As you can see in the picture, they agree fairly well with each other and with the other brand.

So, unfortunately I did receive 1 of the 3D damaged, the screen just will not turn on even after replacing the battery it came with.But besides that, I really only NEEDED 2 and just wanted an extra to have. But the other to work like a charm. They have a magnet on the back, which I do wish was a little stronger but otherwise still great. They come with a little stand on the back and a hole you can use to hand them up with a nail if you’d like. All around a good and accurate product when I tested them out. Just a little disappointed one came non-functional.

Initially, the three thermometers had three different measurements but came closer together after a few minutes. The manual says the temperature accuracy (not consistency) is within 1/2 of 1 degree Celsius. After a few minutes in the room, the three temperatures stabilized within a range of .4 and then .2 degrees Celsius of EACH OTHER (the lower number being as I finish this review). That could be within the stated accuracy of .5 degrees of actual; at least, the numbers are close to the room heater's wall thermostat; I can't say how close because the wall thermostat rounds to a whole integer, not showing decimal values, which the Sonomo items do. The humidity measurements began at 47, 48, and 49 and have now stabilized at two 48s and one 50, so they at least are mostly CONSISTENT. The stated ACCURACY is +/- 3% of actual; I have no other device to compare those numbers to and so can't say anything about their ACCURACY. At least both sets of numbers ended up being fairly consistent among themselves.

They were way smaller than I expected but they are awesome!!! Highly recommend.

I have this as a gift so I don't know what he thinks yet, but I think it will be great.

They are small but I like that. The temp between the 3 units is consistent to approx 1 degree F and the humidity varies by 5% from the lowest reading unit to the highest. That’s good enough for my purposes. The magnet is super annoying because it is not strong enough to hold even the tiny unit in place and it is positioned off center so the unit is constantly tilted at an angle. A stronger magnet would fix both those problems. I probably would not buy these again but they are not so bad that I want to send them back either.

I bought these for my crams habitat. Seems to be pretty accurate, I think. I like that it was a 3 pack. I also have a back up and use one in my basement to keep track of how damp it is down there.Definitely got plenty of bang for the buck.

Small. Instead of three, give me two but larger.
