Love them!! Use them in a large tank for reptile that needs it warm & humid. Because size of tank was hard to determine what both were across the tank as well as what and where to adjust. Nice this provides both, the display is large and works great. I needed 4 for my application, so bonus came with 4. They're easy to see and perfect size. Moisture hasn't interfered with the display.

I have purchased several sets of these hygromoters as my guitar collection grows. I put them in my guitars' cases and they all seem to be fairly reliable, as they barely vary amongst themselves. Fantastic item for such a low price.

Im currently seasoning my new small glass top humidor and wanted to make sure that there was no leakage so I bought these to keep track. When I received them I left two out and put two into my boveda humidor bag to see if the reading was accurate. Sure enough the ones in the bag instantly read 65% humidity which is spot on, being that the boveda bag I have inside is 69%. Will definitely be keeping these handy.

Overall very happy with price and performance. I was concerned due to the variances some customer reported in readings. However the four I got have very little variance - less than a .5 a degree and no more than 1% humidity in a controlled environment. Very acceptable for this price. The units are somewhat smaller than I envisioned, but with a sharp display that is easy to read as long a you are facing it directly. Given the air ports on the back side, I made sure to not cover them when mounting the units on a wall (I used a thin strip of nanotape).Note that temperature is the smaller number, which might be an issue for folks with severe vision issues.Overall, I'd buy these again. Helped me immensely to identify cold spots in the house!

This 4-pack of hygrometer thermometers is great value for the price. I mean, do the math...for not very much money you're getting not one, not two, but (essentially) EIGHT meters. You get all the meters. I have them all over my condo now, checking constantly to show me what part of my abode is responsible for my dry sinuses. I tested one by putting it right next to the humidifier, so I'm satisfied with their accuracy.And as a bonus, the thermometers helped me prove that indeed, there's a ten-degree difference between some rooms in the condo. This is very useful information, especially when trying to convince my friends that yes, it is actually possible to have a ten-degree difference in two rooms that are essentially forty feet apart.So, if you need to know where the desert regions are in your home, or you need good, solid data to backup arguments with your friends, pick these up.

In all honesty, these have been amazing for my Pac-Man tank. The only issue that I found and the only reason why I did four out of five stars was because originally I was using only two of four these meters in my tank. I soon realized I needed to use three of them, and then realized I wanted to use the fourth for another tank.. so I took it out of the package. Everything was normal then I noticed that the fourth one wasn’t quite reading correctly. The humidity number is not portrayed correctly on the screen at all, you can’t even really tell what number it’s at for humidity, I tried taking it out the humid environment and leaving it alone for a few days. Tried putting it in some rice just to dry it out, then in front of a fan. Just in case it was a humidity issue and if something like too much humidity got inside of the meter itself and wasn’t letting it portray the correct numbers on the screen. Tried that out didn’t work. Nothing worked so not too sure what’s wrong with the Hydrometer, though- I’ll say the fourth one itself was acting up before I even put it into the tank, so I don’t believe it was the tank nor humidity that caused the issue of the meter itself. It was also the only one that did not come with a pull tab on the back as well, so maybe that was part of the issue as well?? So that’s why I put four out of five stars for my review. Other than that they work great!! I recommend these highly :)

I wanted to see if the hygrometer I had was accurate so I bought these. We live in a place that's very dry most of the time and I wanted to compare rooms so these will be perfect. Now I can put one in my kids rooms and the living room where we spend most of our time and decide where to put humidifiers. Will update this review on the road.

Good value for the cost. I left the 4 in a Boveda 75% calibration package for 24 hours and they were pretty close to bang on, the Calibre IV didn't fare as well. The caliber is adjustable though. The temperature was consistent and in line with a more expensive temp meter. Just note that if exposed to light the meter will heat up, so if expecting a accurate temperature do it in as shielded area.Only critique is the displays can be a bit difficult to read unless looking straight on, looking at a angle and the contrast is difficult

I was pleased with the accuracy and consistency of these humidity meters as illustrated in the photo. Far better than I expected. I only had one problem. I wanted to put them on walls but the two sided stickies I used would stick to the wall very well (a PITA to get them off the walls) but would not stay on the back side of the meters regardless of which side of the tape I used. One fell off and met its death on the floor so I only have three now. The manufacturer should include some two sided tape that will hold on the back of the meter. I would purchase them again. If they had stayed on the walls I'd have rated them 5 stars.

These seem to work quite well. I opened the package and laid all 4 out next to my existing hydrometer/ thermometer and all 4 were within a degree of temp and a percent humidity of my hydrometer (which I trust). I'm using them in 1L mason jars for curing cannabis. I put 62% boveda packs in the jars and the unit read 63-63% within 24hrs. Does exactly what i need it to do.
