5 Years Old and Still Rocking
I must have bought these 4-5 years ago and they keep chugging. They even came with replacement batteries (which have been needed, but I haven’t had to buy any yet). The double sided tape they come with isn’t the best, but they seem fairly accurate and are easy to read. Great buy for the price I got them.

Simple and effective humidity and temperature monitors
These are useful, we just moved house and trying to figure out our room temperatures, and humidity. These are clear and easy to read, they stick to the wall very easily we put ours just under the light switches maybe next time Iâll get the white colour so that they blend in a bit more but the point is that they work really well.

Fantastic but literally stinks!
They work well, are easy to use and read, and accurately display the temperature. I appreciate their small size and their price. My only qualms are that they are not bright, and to change the battery you have to take the sticky off. On top of that they stink SO BAD when you open them! And it doesn’t go away!

Still Working great after a year of use!!
I have had these well over a year now, I had mold in my house and needed to keep humidity down and these were perfect for keeping track of that! They have a sticky thing on the back you can stick to anywhere (still there over a year) Easy to read and seen to be great quality because they are still going strong and holding up!! Great tool to have in your home for a great price!

Compact and Convenient, but Slight Variations in Accuracy
I purchased this 2-pack of mini digital hygrometer thermometers over a year ago to monitor the humidity and temperature in my reptile terrarium and greenhouse. The compact size is perfect for placing in small spaces without being obtrusive. The LCD display is clear and easy to read, and I appreciate the option to switch between Fahrenheit and Celsius.The devices update readings every 10 seconds, which is helpful for keeping track of environmental changes. And since it came with 2 of them I placed the other in the room where my terrarium was, to monitor the rooms temperature.Overall, these hygrometers offer good value for the price, especially if you need multiple units for different areas. Just keep in mind that there may be minor discrepancies in readings.

Really good deal but maybe not the best for constant high moisture
Probably my setup or defective two, I have dart frogs and my humidity is around 95-98% at all times and I have a fogger, and so because tape doesn’t hold long in those conditions I attached a suction cup. Each worked great, very visible, even through the fog, but after about 6 months each started to fail. Display got dimmer and dimmer over time, battery changes did nothing.The reason why I imagine it’s my set up and the direct exposure to fog is that my wife has had the exact same one with her bearded dragon for well over two years with 0 issues, it’s why I bought them.

Work great! Will be buying more!
These work great! They are accurate and easy to use. The battery life is good as well. I’ve had them on non stop for two months now and they are still working great! I use them in my reptile enclosures and just in my general room to keep track of the temp. Great deal for the price! I will be ordering more for my reptiles.

Works nicely
I was actually touchedâ the two meters came in individual boxes, with an extra set of batteries and two adhesive mounting pads each (reality: you will mess up location or need to replace the adhesive at some point: very generous. The included âwarm tipsâ note was âcharminglyâ translated. So overall, 110% customer serviceâ it seems they want to care :)Now, I work with microcontrollers and DHTâ22âsâ¦. Getting temp/humidity readouts accurate is a challenge! For a $4!product (I got the 2/pack) they are pretty close in side-by-side comparison! Humidity matches, temp is off super slightly⦠if you want to drive yourself crazy, get 4 or 8 and compare. Iâm trying near floor and near ceiling simultaneously now to evaluate how to best install a âheat recovery ventââ want to find the most humid spot(s) to draw air out from. I think I will buy moreâ¦One detail: they are âpanel mountâ, ie you drill a 2â (didnât check, confirm first!) hole and then simply pop in⦠in other words, the rear sensor opening will read behind your panel. For my purposes, a little masking tape loop will allow you to temporarily stick it to surfaces, and it adjusts relatively quickly to ambients (try exhaling 2-3 times close by and it registers!)My guess is itâs a sweet family operation making them.. so far so great⦠but surprisingly humidity seems same too of room vs bottom, had thought humid air risesâ¦

These are fine little devices for the price, but when they arrived, one had a completely dead battery and the other had no battery at all. Other than that they’re OK for the price.

Mit dem entsprechenden Ausdruck für das AMS fügt es sich dort sehr gut ein und gibt wichtige Informationen über die Temperatur und die Luftfeuchtigkeit im AMS.Prima!
