Great set for the price. I've been using these on for a few weeks now and so far they have done VERY well. They are small and discreet, but still easy to read. Set up is super easy as well, and the mounting tape that comes with it has held up better than the name brand rolls of mounting tape I've tried before. The temperature and humidity readings have been very accurate. Amazing bang for your buck.

These mini thermometers have worked just as expected. They’re small enough to fit wherever needed and the display is clear and easy to read. So far, they’ve been consistent and reliable without any issues.Simple to use and great for keeping an eye on temperature and humidity in smaller spaces.✅ Final Thoughts:Does the job with no hassle. Handy little tools to have around—definitely satisfied with the purchase.

These work great! The #d printer enclosures I got both had really garbage meters on then so I installed these and it was a breeze to setup. really easy to read and change to from C' to F' seem to have good battery life and now I can constantly monitor the temp and humidity which is a MUST!

I use these in my incubater and they work well. They work well to show the temperature and humidity in different areas of the incubater. They are simple to use and work well.

Loves these digital thermometers. Perfect for terrarium and works good. Very accurate and inexpensive. Highly recommend

I initially bought these for my brooder box for chickens. They are accurate, excellent value for the price and very durable. They’ve been knocked down, pecked at and stepped on and continue to work great. I ended up buying extra sets and putting them in different places in the house, including our basement, to gauge temp and humidity.

I ordered a six pack for a project that uses this form factor.They are as described. Mine came with an extra battery for each in a separate plastic baggie. Each also came with a double sided round 3m foam sticky.Temperature seems to be range a bit, but within 5 degrees Fahrenheit or so. They all read slightly high. Humidity seems to read a bit low compared to everything else I have, but I'm not sure if that is with these or my other ones. All the working ones were within 1% of each other.Of the six, one is completely unusable. It varies between 9.9C up to 50C swinging about 15 C every few seconds. Humidity never displays. Returning it will cost me a 45 minute trip across state lines to the closest return store or more than half the cost of the lot of six to get USPS to pick it up. It isn't worth returning and I'll have to find a single in this form factor from somewhere else.All of them came packaged loose in a zipper bag. They all have minor scuffs that could possibly be from rubbing together while shipping. These are cheap and I don't think anyone is counting on them looking pretty, but it is worth mentioning in case someone is. They are very minor, but every one of them do have scuffs.

Bought these to monitor humidity in my filament storage boxes and my Bambu AMS unit. All 4 showed the same humidity value. Came with extra batteries.
