    Easy to use, Work Well
    I bought these thermometer-hydrometers for a a few of my reptile enclosures for ambient temp tracking. The displays are nice, and the battery life is pretty good. Size-wise, the product is quite small, but is still big enough to read easily. They function well, but sensitivity-wise, I’m not super sure on how accurate they are. Overall this pack appears to be a great affordable product for keeping track of ambient temperatures, and is a must-have for any reptile owner. One note on them though is that you will want to have Velcro or double-sided tape to adhere them to wherever you want the thermometer-hydrometer to be placed, as they do not come with adhesive.

    works perfect in incubator
    worked perfectly in my incubator!! wanted to make sure i had a second reading of temp and humidity while hatching chicks. these are inexpensive and work great in the incubator and give me peace of mind that the incubator is the right temp and has the right humidity levels

    Work well, but not the last word in accuracy
    For the price these work great. I use them in the AMS connected to my Bambu Labs P1S printer. If you look at all of them next to each other, there are slight variations in the measured humidity and temperature, but that’s to be expected with a hydrometer at this low price point. So, not the last word in calibration accuracy, but usable. My only real complaint is that I wish the readability of the screen was a bit better off-axis, but that’s probably too much to expect here. I should also note that the batteries came pre-installed and the units were on when I opened them, so I am not sure how much of the battery was consumed while they sat in a warehouse. I haven’t had to change the batteries yet, but I expect these will likely not last as long as if they were fresh.

    Super helpful
    Living in Florida, these have been great scattered around our house. They’ve let us know which rooms needed more heat/light blocking.They’re also great when I vale because I can adjust the hydration of my breads and baked goods based on the relative humidity of the kitchen.Even my husband, who has as he says “old man eyes,” can read them.They’re still going strong months later.

    Great deal for the $$$.
    These are wonderful. Not sure of the accuracy but doesn’t matter in my intended use. Just need an estimate of RH.Another reviewer indicated to remove the batteries from ones not in use. That was an excellent suggestion.

    Nice display for your reptile enclosures
    They work well while the last but I dont seem to get more than a few months out of the battery in them. Inexpensive enough I dont mind replacing them when needed. Display is large and can clearly be read so they work well enough for what I need.

    Good, especially for the price.
    I’m using these for tracking the humidity inside of “dry boxes” for 3d Printing Filament. They appear to be very accurate for this purpose. They aligned perfectly with a more expensive temperature and humidity sensor I use for another room. They do not react quickly, and take a few seconds to respond to (and settle on) a new humidity and temperature when moved from inside a box, say, to outside, but this should be fine for most purposes. The units themselves appear fairly robust – I dropped one of them from about 3-feet onto a concrete floor, and there was no sign of damage or any change in functionality. The only complaint I’d make is that the LCD screen can be a little hard to read from certain angles, but overall, these are perfect for what I bought them for.

    Love these
    Really useful. I got them for incubating eggs and it’s so handy to put a few in and get different readings from different corners to ensure proper temperature and humidity. Love that it shows both temp and humidity on the same small screen so it doesn’t take up tons of room. Great value!
