Great product. Works wonderful for my PLA and PETG filament storage keeping them at 10% Humidity. Accurate, easy to see and no issues. All 6 are in different containers and they all show same results. Love it. Great price for the value.

Alright, so a lot of people have written reviews for these little hygrometers and it doesn’t seem that a good majority of folks are using these for their cigar humidors. I’ll go ahead and let folks know that I bought the specifically for my desktop humidor. And I want to say that that so far in the week or so I’ve had these units. They seem to be working perfectly. First thing I did was do a humidity test and calibration using a BOVEDA calibration kit see picture below. These two little hygrometers consistently read at 75% to 76% humidity, which was right on par with what the test was. So for me, at least these units came as close to perfectly calibrated as possible right out of the box. They’re small easy to read and do the trick. Personally, I think there’s no need to go out there and buy a fancy expensive one unless that’s what you want. These two just fine for cigar humidors, and for telling the humidity wherever you may need it. Please keep in mind this is for me and my experience only your mileage may vary.

I needed a good Hygrometer the keep track of the humidity and temperature in a reptile enclosure I have with a sensitive critter, I installed this hygrometer and I was amazed at the accuracy, it’s amazing how well it works, it also came in a 6pack so I can monitor some other cages as well, the temperature gauge is very accurate as well , it’s also the perfect size to fit in a convenient area and not be in the way ,I highly recommend these for anyone in need of a good hygrometer

They work fine for what I need them for. I gave it 4 stars because it is not 100% accurate. If you are purchasing for a reptile tank, please invest in a heat gun as well to double check the temps.

I picked up this 2-pack hygrometer/thermometer to keep an eye on humidity levels in a couple different places, and they’ve been working great so far. They’re small, lightweight, and easy to place just about anywhere, which makes them really convenient for jars, storage bins, or small spaces. The display is clear and easy to read, showing both temperature and humidity at a glance. I like that you can switch between Fahrenheit and Celsius depending on your preference. The readings seem accurate as well—I compared them with another humidity monitor I already had and they were very close. I’m currently using one in a storage container and the other in a small indoor setup, and both have been consistent with their readings. For something this compact, they do exactly what they’re supposed to without any complicated setup. Another nice bonus is getting two units in the pack. It’s useful to monitor different areas at the same time, whether it’s for a greenhouse, reptile enclosure, humidor, or just general indoor humidity tracking. Overall, these are simple, reliable little meters that get the job done. If you need an affordable way to monitor humidity and temperature in small spaces, this 2-pack is definitely worth it.

This pair of hygrometers is budget-friendly and, when compared to a third humidity meter, is accurate to within one or two percentage points. A nice, inexpensive purchase that gets the job done. I use one of them inside a hard-shell guitar case, holding a pricey acoustic guitar, to monitor humidity levels within and alert me upon opening the case if it deviates more than a few points from a 50% humidity target. I'm happy with this purchase.

Fine I guess for the price but I question the accuracy. The thermometers are giving different readings even when sitting right next to each other.

Accurate and battery has lasted me a long time. It’s been 9 months and still haven’t needed to replace it. I keep one in the car and one in the kitchen. Lowkey want to buy some more.
