works well

AgonDecember 28, 2025✓ Verified purchase

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. Read more

Budget Friendly Pair of Accurate Hygrometers for an Acoustic Guitar Case

R JordanFebruary 23, 2026✓ Verified purchase

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. Read more

Works as described

LwoodJanuary 30, 2026✓ Verified 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. Read more

Inexpensive and work well

Good for reading temp/humidity in bearded dragon’s cage

meganDecember 28, 2025✓ Verified purchase

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 Read more

Very handy and a real bargain.

Coffee LoverFebruary 13, 2026✓ Verified purchase

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. Read more

Works, just change batteries when you get it.

PropofolFebruary 17, 2026✓ Verified purchase

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. Read more

Work as intended

Life-sized humanJanuary 1, 2026✓ Verified purchase

Only comes with extra battery per (listed as 2), and drastically different readings for one of them. Amazon isn't letting me upload the pictures, will try again later. EDIT: After a day, they all seem to have normalized. Changed from 3 to 5 stars. Read more
