2pack Mini Digital Hygrometer Thermometer, Indoor Humidity Monitor, Temperature Humidity Gauge Meter with Fahrenheit (℉) for Greenhouse, Garden, Cellar, Closet, Etc by AikTryee

Got these to determine the humidity in a couple of areas where we were smelling some mildew. This helps us control the humidity and know when to turn on the dehumidifier. Rather than have a big dehumidifier machine out all the time, these two tiny little humidity monitors let us know any time what the humidity levels are in different areas. These are accurate and work very well. Highly recommend.

Wanted something to measure the humidity in the house. Also decided to test out the fridge temp and humidity level. They work great, great deal, small so I can have it set somewhere discreetly and keep an eye on the temp in the house. Comes with 2, replacement batteries and sticky tape if you want to mount it somewhere. Recommend.

These are working well and seem to be accuracte. I use one to monitor the humidity in our RV and another in the garage. A back light would be a great addition but happy otherwise.

When they work, they're great. However, the screen is glitchy and will go in and out so you can't read it, and they stopped working within 6 months.

!!!! incredible listing !!!!incredibly cheap so my expectations were not high at all but not only did this come with two hydrometer/thermometers but it also came with batteries in them already, extra batteries, AND velcro already measured and cut to the size of the little readers. really an amazing buy :) they both read the same humidity and temp so i assume they’re both accurate, they’re nice and small so it’s easy to make fit in any tank, but the numbers are nice and bold so it’s easy to read. highly recommend :) took two seconds to stick em in my tarantulas tank

It would be perfect. I mean the low cost meant i knew it wouldn't be 100 percent accurate but it was pretty darn close. Plus it comes with velcro patches to stick em anywhere. My only problem is once you open the back to battery's it almost impossible to get it closed back tight enough to keep the power on without tape which is annoying but you get what you pay for and its decent for the price. 98 percent accurate. The quality is defenitly 4 star at best. Looks small and sleek. Battery life seems great. Id buy em again.

Came with batteries installed that were already dead. Then a package of replacement batteries. Put the new batteries in. The thermometer lasted 5 days in my leopard gecko tank terrarium and 7 days in my egg incubation tank.A product of ANY kind should last longer than a week. How unreliable, and what a terrible waste of money.

We were having humidity issues in parts of our house. So, we put one of these in there and observe what is happening.
