These work great and having the humidity helps me state my case. I work in buildings that refuse to turn on the A/C for works and I can use these to hold them accountable to OSHA regulations! They can’t argue with me when I show them to their face the temperatures they are making us work in! No excuse now!

use these to help keep track of humidity in jars while curing cannabis. cheap and invaluable to the curing process, i try to have more than i need ready to go. back in the day growers didn't use these for curing but of course we've learned a lot since then, and it's good to get the process dialed in as much as possible. for me with my ADHD, these are a no-brainer.

These are great little hygrometers. They aren't perfectly accurate but they're very close and usually have a margin of error around plus or minus 2%. I used them around the house when we were having issues with high humidity to pinpoint the most humid areas and manage it with a dehumidifier. I also used them in a small enclosed hydroponic set up I use to grow jalapenos.They're small and light which makes them really easy to hang on a wall or make a small cut out in plastic for. I learned that you shouldn't block the back of these as well as that is where the sensor reads the humidity from. There is a small array of holes on the back that you have to make sure have proper ventilation to get an accurate reading.The display is really easy to read and they function on one battery for ages. I haven't had to replace the battery in any of them and they've been going for about 5 months.Overall I would recommend these for the price and quantity and I'll probably get them again.

It’s nice to have these spread out around the house to get a better read than the thermostat.

Small but mighty. These work great to see how much humidity we have in our basement so we can then do something about it.

Purchased a 6 pack but one of them came defective. Other than that they are good products. They respond to changes fairly quick.

Perfect little meter for what I need to know about my smaller, unconditioned spaces (like closets & rarely used rooms). Using them to keep track of humidity in closets & keep clothes from smelling from moist conditions. Especially needed in spring & fall when the heat & AC are not running as much & house humidity levels can spike. Bonus that it tells the air temps also. Got the six pack to have backups for when the batteries run out or they break. Batteries are replaceable.

I didn't realize how small they were but dang do they work well. They also work super fast and are very accurate. Greate purchase and has a larger print to make it good for a quick reading!
