These little sensors are so cheap and affordable that I am worried they'll break. But lo and behold, still going strong. I was also concerned they wouldn't be accurate or precise but in all of my testing, they've passed with flying colors. Read more

They function great, but are incredibly fragile. Be careful if inserting them into a housing, they may come apart. Read more

These work great if you need to monitor the temperature of any items. We put them in the bags with our "herbs", and they kept the temperature right where it should be! Read more

Everything was great except the batteries were already running. That being said were they just activated or have they been running on a shelf somewhere for 6-8 months? Other than that nice size and currently working. Read more

It made a really big difference to know the humidity inside the jars was correct or not in order to take action if needed. Super easy to use kind of idiot proof to be honest. Read more

These are nice hygrometers that have many uses. The quality is decent for the price point, and they all seem to be reasonably accurate and track together. I haven't tried calibrating them to a national standard for accuracy, but they aren't labeled as NIST certified, so that's not really an expectation. The humidity values track within 1% of what I'm getting from electronic equipment with internal sensors, so I'd say they're accurate enough for anyone looking at one of these for hobby or home use. The price for them seems fair as well, as they work out to be about $2 per piece. Read more
