Mini Hygrometer Thermometer Digital Humidity Meter Indoor/Outdoor Humidity Monitor Reptile Thermometer for Humidors Greenhouse Garden Cellar Fahrenheit(℉)/ Celsius(℃) 2 Pack

I thought these were perfect for our little chicks while we had a bulb up for them. It gave us a pretty accurate temperature reading. We could insure they were comfortable and not too cold. We put them high enough to where they couldn’t peck at it but still was very effective. They held up the whole time and have a good battery life.

These are pretty good, I have them in my jumping spider's enclosure, They're pretty accurate and not too big where they take up too much space.

These work great for monitoring humidity around our 3D printer! We have one in the storage container, one next to the printer and one on the shelf with our prints. Easy to use and easy to read.

I ordered the two-pack of these.They arrived with two 3M sticky pads, but, oddly, only one spare battery.It seems from the reviews that mention it, that normally there would be a spare battery for each hygrometer, so there should be two. I guess any number of spare batteries is still a nice bonus.The hygrometers seem more or less correct.The two are both in the same range, but they don't quite agree with each other.For instance one might read 67 degrees and 55% humidity, and the other one, right next to it, will say 69 degrees and 53% humidity.The differences are small, so for a non-critical application where I just need to know roughly what the conditions are (like a humidor) they seem like they're good enough.

They seem to agree with what the smart thermostat says and react quickly to changes. Nice and inconspicuously small to double check what the humidifiers are doing in winter so we don't condense the windows. Haven't run them long enough to know what kind of battery life to expect.

I really like this item. I needed something handy for my resin room and these just fit the bill. Came as a pack of 2 and my vision not being what it used to be they are perfect for putting near my work area. They are small so not in the way but easy to read so I get the info at a glance and I really like them. Being able to see the humidity level helps ( I live in Mississippi 🤪). Would recommend to anyone needing that info at a glance

I ordered a six pack for a project that uses this form factor.They are as described. Mine came with an extra battery for each in a separate plastic baggie. Each also came with a double sided round 3m foam sticky.Temperature seems to be range a bit, but within 5 degrees Fahrenheit or so. They all read slightly high. Humidity seems to read a bit low compared to everything else I have, but I'm not sure if that is with these or my other ones. All the working ones were within 1% of each other.Of the six, one is completely unusable. It varies between 9.9C up to 50C swinging about 15 C every few seconds. Humidity never displays. Returning it will cost me a 45 minute trip across state lines to the closest return store or more than half the cost of the lot of six to get USPS to pick it up. It isn't worth returning and I'll have to find a single in this form factor from somewhere else.All of them came packaged loose in a zipper bag. They all have minor scuffs that could possibly be from rubbing together while shipping. These are cheap and I don't think anyone is counting on them looking pretty, but it is worth mentioning in case someone is. They are very minor, but every one of them do have scuffs.

Love them, easy to install and use. And they work great, and last a long time in a battery.Printed some holders to go into my ABS on mu 3d printer. Use these to see how my filament is doing. Great little devices that require no real effort to set up and use.
