Humidity Meter Indoor Thermometer 6-Pack Mini Digital Thermometer Hygrometer Indoor Temperature Humidity Meters Gauge LCD Display Fahrenheit (℉) for Humidors, Greenhouse, Reptile Tank, Cellar, Closet

I haven't had these long, but so far they are fantastic and doing exactly what I need them to do. I needed to figure out if specific places in my home were the right conditions for a few different plants. I got these to make it easy. Their small size allows them to go anywhere without taking up space. I jabe compared them with another Thermometer i know is accurate. The accuracy of these thermometers is spot on. I am guessing the humidity level is also spot on, but I dont have the ability to compare it with something elsw, so I can only guess it's right since temp is right. The magnet strength is great as they haven't moved a mm. I haven't had them long enough to comment on their durability. I will update at a later point on that. The price is right, if I need more I will definitely buy again.

Buen producto, cumple con lo que promete.He probado estos medidores y la lectura que ofrecen es bastante precisa. Los comparé con equipos de otras marcas más reconocidas y los valores son prácticamente iguales, así que cumplen con su función. Son fáciles de usar, la pantalla es clara y el tamaño es ideal para monitorear varios espacios. Buena inversión si buscas algo simple y confiable para medir humedad y temperatura.

Good: seem to work, easy to read, probly accurate. Batteries are easy to change.Bad: they were on when I got them, so who knows how long the battery will work. Smaller than I thought they would be.I opened up the back of a few of these and disconnected 1 of the 2 batteries, so they won’t die out on me sitting in the drawer. I like these, I would buy them again.

I was pleasantly surprised how accurate these humidity meters turned out to be. I have a weather station and they were very close, within 2% of the reading on the station for the inside. I'm using them to monitor the humidity in dry boxes for my 3D printer filament. I just ordered another set. And the price is good as well.

Not bad for the price, I personally had to place in a ziplock with a calibration pack for 3 days, each unit had a different reading so removed batteries for 30sec and placed back in the ziplock bag About half calibration was successful, the others I had to remove the batteries again for 30 sec then replace in the ziplock again, the next day they were within 1% of the humidity.Slightly smaller than expected which is good in my case. Very easy to read and understand .Quality seems ok,

I’m always super skeptical when it comes to buying cheap things like this. I bought two packs. Every single one works great. A few are a couple degrees off. Will buy again!

Chesp as chips, work great.

Six of these devices all agree with each other to within less than 1% humidity and 1 degree (F) in temperature. Pretty amazing! Users might wish to know that these are designed to be panel-mounted, though they work fine as free standing units.
