All Three Measured Very Closely With A More Expensive Thermometer & Hygrometer
I was initially reluctant to buy these because of the poor reviews from some people based on poor accuracy, but I had a very positive experience. I had a larger digital thermometer and hygrometer that I trusted. I allowed the three new units to stabilize for a few hours and then compared them to that presumed accurate source:Reference: 87 F & 45% RHUnit 1: 87.1 F & 44% RHUnit 2: 87.0 F & 44% RHUnit 3: 87.2 F & 45% RHThe measurements from all three of the units I received were very close to each other, both temperature and humidity, and also agreed very well with a different and more expensive thermometer/hygrometer. The accuracy seems good and the build quality was surprisingly good considering the low cost. The three spare button cell batteries were a nice touch. I hope I don’t need to replace them very often. I assume not because the three units were all powered on and operating when I received them so presumably the battery lasts a long time.

Perfect fit for many designs on MakerWorld
Works great. The top unscrew and you can remove the diffuser which is useful for prints that include one in their design. It always turns on set to solid red, which is deducted 1 star for. If it turned back on in the last setting and had a power adapter that would be perfect.

Great!
They work! Theyâre very small and itâs nice to have a few around our apartment so that we know how the temperature and humidity vary. We mainly got them so that we will know if we need a humidifier or not. After a few months of use, theyâre still working and have been highly accurate.

Good company.
Works fine and within spec it seems. comes with 3 extra batteries and a small card that says if a product does not work to contact them to receive a replacement. My first impressions is that this is a company that cares about its product and reputation which usually leads to a good experience for the consumer.

Small and mighty
These small but mighty devices provide accurate temperature and relative humidity in an easy to read and discreet package. I measured all 3 against each other and they were well within their stated error range. I found these perfect around the house for taking point measurements in rooms to fine tune my HVAC system, and even in cabinets to find the best (coolest) place to store medication. Hint – it’s not over the refrigerator! These appear to be ideal for replacing the devices in humidors given that it’s the humidity which is the large number – not the temp – but that was fine for my application. Temperature can be displayed in F or C, as desired. These also came with 3 extra batteries (plus batteries installed). Great and accurate for whatever your use case even if you don’t own a humidor.

Dont Buy Low Quality
These were not very accurate after calibrating my humidor sensor. I added these as an additional sensor to my humidor. They were off by 4 to 5%. Not happy with the products
