> 3 dayEDIT: Using my infrared heat gun, these were 1-2 degrees off. Not enough to matter if youre using these to gauge growing plants or keeping temperatures for a pet terrarium or similar function, but worth mentioning. Either that, or the heat gun is off. I have no way to calibrate either to know which is 100% perfect. Original post: I cannot confirm accuracy, but from using these around the house the past few weeks Id say the temperature is accurate. Both read pretty much exactly the same for temp and humidity when they are near each other. if I breath on them, the humidity level jumps quickly to 100% (OK, it only has 2 digit places so it stops at 99%), so I think they are close enough for my needs. My needs? I have a bearded dragon and that means I need to have live insects to feed him. So I have to keep the insects at a steady temperature and humidity level so they are healthy when it is time to feed my dragon. So this is perfect. I cut a little rectangular hole in the bin, pop this in and these batteries (if they are anything like the last ones I owned) will last for a few years. They sent extra batteries, but goodness knows if Ill know where they are when these original batteries eventually give out. I only needed one, so I took the other upstairs to the bedroom. The humidity was really low (its winter now), so this helped convince my wife that we needed a humidifier in the house. The first was too small, but my wife told me this morning that she could tell a difference in how she felt the following morning after the humidifier was running. I may toss this into the bearded dragon terrarium too. They need to be kept at a certain temperature and humidity level too.

> 3 daytemps and humidity not accurate and mounting method sucks but does an ok job for the price and general location. it should not cost that much!!!!!

> 3 dayI use them in my humidor and they work great as a supplement to my analog one. They are always within a degree of each other so I am ok with the variance. They are so small so next I will add some velcro to the back and on the humidor so it can stay. I forsee alot of life from these and if not, they were cheap enough that I would buy again. Perfect for what they are made for.

> 3 daynot the most accurate gauges ive ever used in my life but 2-3% off is close enough for my needs

> 3 dayThese temp/humidity gauges are perfect for what I need them for, my praying mantis enclosure. So beautifully simple & cheap, but not poor quality! These are very sturdy & very easy to place due to being small. But not so small that you cant read the screen. They are perfect.

> 3 dayIf these ever actually die or use up the extra batteries I will buy the same ones as replacements. Just replaced the batteries in one and I’ve been using them for 11 months now. The one with dead batteries has been working overtime. It’s in a basement. In Florida. On waterfront property. So it’s been reading 99% humidity the entire time. The poor little thing is probably as exhausted and overheated as I am! I still have one more set of batteries and the other meter is still going strong. I can’t think of the last $5 I spent that lasted as long as this pair of hygrometers! They are probably not accurate enough to conduct college thesis scientific experiments, but they are CLOSE. And that’s all I needed - to get an idea of how the humidity levels in the basement compared to the rest of the house and how those levels change with the seasons and rainfall. I think the humidity readings are more accurate than the temp readings, which sometimes showed ~4• off from the thermostat BUT my purposes are really for the humidity readings. Totally satisfied with this purchase and will buy same ones again if/when this pair quits or the batteries all die. Probably the extra batteries alone are worth the total cost. #battery life excellent #accuracy close enough #happy customer

> 3 dayIt’s the second time I’ve ordered some of these digital hydrometers and they really work great and I was not expecting to have the extra batteries which is a huge plus for me. It’s always hard for me to keep up with batteries and now I have some extra ones, keep up the great work

Greater than one weekGood cheap Hygrometer, The double sided tape it comes with is poor quality, use Gorilla tape instead.

Greater than one weekSturdy and stayed stuck on glass terrarium wall. Seems pretty accurate as they both matched up together before being placed in the terrariums. Placement for the sticky could be better or a permanent way of sticking as when the batteries need changed, it’ll have to come off, but that could also be a user error on my end. Overall recommend.
