6-Pack Mini Hygrometer Indoor Humidity Meter, Mini Digital Thermometer Humidity Gauge Meter, Indoor Thermometer Hygrometer Monitor Fahrenheit (℉) for Reptile Thermostat, Jars Reptile, Fridge

I'll jump in with the pros and the cons. There will be some overlap.Pros:- A cost effective solution for knowing the temperature and humidity level. Considering you get six of these guys, it's an amazing buy.- Small and compact measuring approximately 1.875 by 1.25 inches. Numbers are easy to read with the humidity number being displayed most prominently.- Fairly accurate. Measuring them against each other on my desktop, all read between 68.7 and 69.4 degrees F with humidity registering 36-38 percent with one showing 36, three displaying 37 and two showing 38. I'd note I do have a small heater running at one end of my desk, so this to me falls into the fairly accurate for the price category.Cons:- No way to calibrate.- These were designed to clip into something, though I don't know what. There are clips on the sides of the units.- While they are free standing, there is no way to set them at an angle.- They do feel pretty cheap, so durability and battery life are questions I can't currently address.Recommendation? Yes, I think I would recommend them for simple, basic information. I intend to put a few of them into my seed starter trays to keep an eye on humidity and temperature when I start my plants, so who knows how they'll do in that warm, humid environment. But I'd order them again given my overall first impressions.

I bought this 6 pack and every single one of them is working great ! Some of them may be 1 percentage point off every now and then then but they all stay really close to the same measurement, and I have other humidity gages right next to them to verify the correct humidity within + or - 1% Yes these are a good value for your money.

Used these inside of an incubator without a humidity control to hatch chicks- I found that every so often it would suddenly read 10° on humidity, but as soon as I popped the lid to check, it would shoot up to 40%. So I think the 10% readings aren’t accurate - which can be an issue if you are trying to keep humidity higher without disturbing your eggs particularly during lockdown. It caused me a fair amount of stress, but thankfully, it worked out OK in the end. However, I would probably put more than one inside of an incubator just in case. Also, I found that the humidity would jump around sometimes, but other times be static for 12 hrs or more so again not sure on accuracy. Temp seemed to hold well though.

Works great. Clear digital screen. Accurate reading. Small and looks good. Doesn’t take up a lot of room.

Small, convenient, great price, works great. Buy with confidence.

The meters arrived together in a single box and were already powered on.When I previously ordered from another vendor, each meter came individually boxed with a plastic tab to prevent battery drain until first use. With these, there's no way to know how long they’ve been sitting on a shelf running or how much battery life remains.The listing claims high precision monitoring with a humidity accuracy of ±5%RH and temperature accuracy of ±2°F, updating every 10 seconds. However, across the six units I received, the readings varied:Humidity: 17%, 20%, 15%, 18%, 18%, 20%Temperature: 70.5°F, 72.1°F, 71.4°F, 70.7°F, 71.9°F, 71.4°FWhile the temperature variation is within the stated accuracy range, the humidity readings seem inconsistent, with a spread wider than expected.That said, these were half the cost of the others I ordered, so time will tell if the savings were worth it. If accuracy and battery life matter to you, you might want to consider spending more on a higher-quality option.

Great bang for your buck there cheap and decent amount come. they function good seems to have good accuracy easy to use shows the temperature and humidity just try not to get them wet or they break easy .

PERFECT! Tested the accuracy of these by sitting it on top of my home thermostat. They red almost Identical for many days on both humidity and temperature. The display is very easy to read and the unit seems to be durable enough for indoor conditions. I use it to monitor the climate in my 3D filament dehydrator and it works great!
