  • Good for casual use
TLDR; don’t expect pinpoint accuracy, but it’s reliable for general readings. Good purchase for its price point. I have no need for scientific measurements; I just need to make sure the air is wet enough for my plants without spending an unreasonable amount. If you buy a pack of two, you notice the two will show different readings for both humidity and temp, and there’s not really a way to calibrate these. However, the readings are still within 1 or 2 degrees of each other. And from testing by transitioning from normal room humidity to the inside of my tropical plant enclosure, it’s definitely able to pick up the changes in humidity within a minute or so. Another note: leaving these in 90%+ humidity for a long time (maybe 6hr+?) will cause the display to glitch out and become unreadable. Moving the device back to lower humidity will fix it if you wait a bit. And if not, just remove the batteries and put ‘em back. That usually fixes everything. ... show more

  • Replace Instead of Trying to Change Batteries
I have 4 of these and they all work great. They all are within like 1 degree accuracy of each other. I use them for my cigars. The batteries died on one and I didn't know these had replaceable batteries. So I went and bought new batteries. It's a tough time changing them. Well the thing doesn't work now. Sometimes it will have power to it but as soon as I put the battery cover back on, nothing. So instead of replacing batteries, considering the price, I'll just buy another one and maybe I'll be able to change the batteries on my other units. ... show more

  • Plant mom
I wanted a couple I could move around on my plant rack! They seem to work. I'm assuming they are accurate. The 2 pix. One is near my humidifier and one near my succulents and there's an obvious difference. They were inexpensive and came quickly! Good enough for my purposes. If you need this for a cold blooded creature or expensive prized alocasia I would probably buy something else! ... show more

  • Very Helpful
I got this for my new crested gecko and new hermit crabs. The product was already on and working out of the package. The package came with extra batteries and 3M adhesive to stick to. I used Velcro command strips for mine. Would recommend for anyone who needs to track temperature and humidity!

  • Batteries on both thermometers needed replace a couple of months after purchase.
Works for what I am using it for. (Monitoring 3D printer Filament in storage).

  • Simple, effective
Does what it says on the tin. Simple, easy to read, and reasonably accurate.

  • Accurate but takes some resetting and a little bit of patience
As others have stated, the hygrometers were operating out of the box since the seller already stuck the batteries in before shipping it out. They're small, light, and have a clear and easy-to-read LCD screen. I bought them to monitor humidity in my guitar cases, so their size and lightness are perfect for fitting into the little available space around the guitar and I'm not afraid that they'll do any damage to the guitar if they come lose from their adhesive on their own (although it'll be a different story if its from something like the guitar case being jostled around). They also come with double sided 3M tape strips and a new set of batteries per unit which makes this a very good deal. Also as noted by another reviewer, almost the entire back side of the unit is occupied by the battery door which means ideal places for mounting are limited to the narrower sides. While this made mounting a bit more finicky, there's enough surface area to be able to securely adhere the double-sided tape to the top and to the desired surface. It doesn't feel like it'll come off unless I really pull on it. Out of the box, there was about a 1-2% humidity difference between the two units I purchased and temperatures were about .5-1 degree off. I reset them as specified by the seller in the Q&A's by removing the batteries and leaving them out for about 10 minutes before putting them back in. After the reset, the difference in numbers was the same, but after about 5 minutes of acclimating and letting them sit side-by-side on their own, they matched each other exactly. I'm assuming that the initial number differences may be due to very sensitive sensors that are reacting to the heat/moisture of your fingers after handling. I also think that the units do take a few seconds to register any changes in humidity/temperature, but that works perfectly fine for my purposes. For example, if you're moving it from a humid greenhouse to a dry exterior then you'll probably have to wait a few minutes for the numbers to gradually ramp up/down. If you want more responsive hygrometers you may need to look elsewhere, but if your monitoring situations aren't critically dependent on instant read numbers, then this is a perfectly adequate solution. ... show more

  • Accurate and well worth the price!
I use several of these to monitor humidity inside musical instrument cases. I occasionally check their calibration using hydrated potassium carbonate as a standard, and I have never found one more than one percent high or low. Allowing for the value of the four spare batteries if you bought them at a drugstore, the devices themselves are almost free! ... show more
