I NEVER give five stars. Yet I did for these. These are remarkably accurate and consistent, both the thermometer and the hygrometer. Multiple units are within 1 degree F and 2% humidity. I still cannot believe how uniform these units are. I have bought 6 sets of four -- 24 in total and each and every one shows the same readings to +-1F and similarly +-1-2%. Formal dispersion in readings amongst 24 units is After researching a huge number of the small temperature units on Amazon, I decided that the vast majority were Chinese junk. Expensive batteries, bad design. Inaccurate. Yet these units demonstrate that Chinese companies can produce a well-thought out product that is very well-engineered and can be manufactured to a high degree of consistency. These stand out for their excellence and are a credit to the company that designed and manufactured them. I think they are worth paying more for. I sincerely hope that the company does not lessen the quality in search of the lowest price. That "race to the price-bottom" destroys so many Chinese products. It is good to find a product that demonstrates that Chinese companies can do "excellence".

I've had these for almost a year. They record the temperature and humidity correctly. I'd buy it again

As my plant collection slowly spreads throughout the house, I needed a cost effective way to monitor temperature and humidity in multiple areas. These little guys fit the bill beautifully!They are very simple to operate and the display is quite easy to read despite their unobtrusive size. They have a little kick out stand on the back for flat shelf placement. They are also magnetic and stuck well to every metal surface I tried them on. It took less than 30 minutes to get all four to acclimate to the house after activating and offer four identical readouts. I checked their displays with other temp/humidity devices and am confident that the readings they're providing in their permanent placements are accurate.These are exactly what I was looking for and I'm quite happy with the purchase.

They all came in good shape with your standard plastic battery disconnect. Three of them turned on immediately upon removing that plastic shim and the fourth one did not. Taking the battery out and in turned the fourth one on..I had purchased a pack of six for $10 that were widely off on both temperature and humidity with each other and returned them. This is a pack of four for about $15 so not as good a deal, but probably average compared to other offerings and after the fix below, appear to be working very well, thoughI have no idea of battery life at this pointAt that point I let the readings settle for about 30 minutes and the humidity readings were within a half a percent on all but on one the temperature started 6° higher and kept climbing until it was 10° higher. At that point I put one of the other three and the one with the abnormal temperature into a refrigerator as I remember reading a long time ago that can sometimes reset the thermocouple providing that measurement.After a couple hours out of the refrigerator, all the values normalized and the temperatures then were within in half a degree.These consistently read 3 to 4% less than a home weather station sitting right next to it but they are consistent with each other. The temperature is consistent with each other now for a day and within half a degree of the weather stations reading.The temperature issue on one is why I deducted the star otherwise these all come with a magnet, not too powerful, and I really needed double-sided foam tape to put inside of 3-D printer humidifier but otherwise these have large readings for both values and are easy to read although they’re not backlit.I’m eventually happy with the purchase and recommend a do buy.

Long lasting battery. easy to read. I left it in my car in -10` F temperatures and it still works just fine.

I got these for my beardie enclosure. I only needed 2, but yeah, my kid ended up claiming one for his bedroom and I have one in my office too. They seem to be accurate

With temperatures consistently well over 100 degrees here in NorCal, I was not sure if my home ac thermostat was accurately reading my inside temperature. Wanted to check and verify if it was or was not reading accurately before I decided if I needed a new thermostat. After scrolling for and dismissing several other indoor thermometers based on customer reviews I came across these. Customer reviews were by far the best out of any others that I looked at.Was not disappointed. Let them sit on top of the thermostat for awhile to see if they all aligned. Pretty much dead on to what my thermostat reads. At this point I would highly recommend.And thankfully I do not need to replace my thermostat

These seem to be nice little instruments but they are basically throw-aways because of an incredibly stupid battery door design. The door is held in place by the smallest Phillips screw I have ever seen and a tiny screwdriver is provided. The screwdriver is made with cheap steel, apparently not even heat treated, and is absolutely ineffective at getting the battery door open. So, when the battery dies, the instrument dies.FWIW I am well experienced with small screws. I have an excellent set of Japanese-spec Phillips screwdrivers and use them frequently on projects. This product's design and junk tool are below anything I have ever seen. If a buyer happens to have a set of tiny high-quality Phillips screwdrivers he may have a fighting chance but the ordinary person is going to own four dead instruments as their inaccessible batteries die.

Excellent! I have them placed throughout the house, including one in my greenhouse, and they accurately record the exact temperature and humidity. I tested them with other instruments to check their precision, and they’re quite accurate. They also record max and min temperature and humidity, which helps me keep track of conditions in my greenhouse. The batteries seem to last a long time, and I also like the design and color, which make them easy to place anywhere without standing out too much. Absolutely recommended

Ich habe für mein Treibhaus eine günstige Anzeige für Temperatur und Luftfeuchte gesucht. Dieser Artikel erfüllt diese Aufgaben perfekt. Praktisch ist der Magnet, mit der die Anzeigen einfach befestigt werden können. Ich habe eine Flachstahlstange mit in den Blumentopf gesteckt und dort die Anzeige einfach magnetisch angebracht. Top Produkt und zu einem günstigen Preis. Vor allem, weil es ein 4er Set war.

Sehr gut finde ich den Magnet der auf der Rückseite angebracht ist. Dann kann man mittels Metall Blättchen (nicht im Lieferumfang) den Thermometer platzieren wie man gerne möchte. Ich würde die Teile auch wieder kaufen.

Happy with these for checking moisture content . Like previous reviews have mentioned they seem accurate, bought four and placed them all around the house with various readings then when placed together they ended within 1% of each other. They are quite small which is not a bad thing as they don't stand out to much. Would buy again
