These humidity and temperature meters are accurate and easy to read. Setup was quick, and the readings update fast. Perfect size for small spaces and great value since you get two. They also include 2 extra batteries so it should help last a long time. There is no backlight so it hard to see at night.

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.

All 6 work as described I did notice a couple have a difference in accuracy between them but not to far off, the items have batteries installed and also comes with a spare set for each. Overall satisfied.

These are pretty accurate. I use them to keep my humidor's hygrometer honest. Inexpensive and work well. Would recommend

Simple product. Does what it claims.. nothing more, nothing less. It’s very small and discreet, so you can put it anywhere without it screaming “I’m a gadget.” No apps. No Bluetooth. No Wi-Fi. No permissions. No geofencing, data harvesting (looking at you, smart everything). Just a basic hygrometer and thermometer that works. Sometimes boring is perfect.

These work ok. Not sure how accurate they are but they all register within a degree or percentage point of each other and for my purposes that’s good enough. I use them to gauge the effectiveness of my humidifier and in the kitchen to check the temp for my sourdough starter and bread dough proofing. So if you don’t need extreme accuracy and other bells and whistles, I can highly recommend these.

Seems to work so far. However, one arrived on and the other arrived with the current battery dead. So the extra batteries seem to be because the button placement on these means any pressure on the packaging turns them on/off, so you'll probably need to replace the battery right off the bat. Button placement is also an issue when you put place it against a wall, as again, any bump or pressure into the wall means it'll change from F to C and/or turn it off. Be gentle and change the batteries and it'll be fine though.

Working so much better than the other ones that came with my bearded. These are reading the temps and humid more accurately. I like that they come with batteries in them and then two extra as well. They are both very easy to read. They are the perfect size and don’t take up much space. They come with an adhesive to stick to the tank and that’s holding up well. So far so good. I’d recommend these
