These are absolutely perfect for a jumping spider enclosure as they are small and compact. There is enough space on the back of the units that allow you to place magnets (not included) to secure to the side of the enclosure. I recommend magnets, not the following.It came with two sticky dots (for the purpose of spiders I do not recommend) as well as two additional batteries. My units already had batteries inside of them.The display is great and very clear, and the temperature and humidity readings compare to other thermohygrometers that I have, responding quickly to changes in both temperature and humidity.

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.

Great product!! I love being able to have these around if needed. I bought a 2 pack and they gave me 2 2-packs!! 4 in total! Awesome experience overall. The product seems very consistent all 4 were left together overnight and in the morning they all had the same temp and humidity! So very precise

I used this for my 3D printer AMS units. They fit the Bambu Labs AMS dryer kit print perfectly. Now my only issue is these won't guage anything under 10%. So unless you go over 10% youll have to read your AMS humidity level on your AMS directly but still this is a good back up guage.

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.

They are pretty accurate. When i opened the package all 4 hygrometers were turned on . also comes with extra batteries and 4 circular stickers to place on hygrometer.

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.

These are the best! I’ve bought so many I’ve put them in all my pet enclosures. The one thing is that if you get any water or dirt on the sticker before attaching it, it will not stick well and you will most likely have to use something else to attach it.
