Cost effective and accurate

Tested with salt and distilled water, they all settled in within 1% except 3 of them. Those rotten things were 2% off. That was sarcasm, I was very impressed with them. I've got a calendar reminder to retest them in 6 months, I'll try and remember to update this review on accuracy and battery life.

Great Value

I bought these to measure the temperature and humidity in my home after installing a ductless AC system. I bought 12 of them and put them throughout my house. They were all accurate and work really well. They are small enough to tuck in anywhere without being obtrusive. I don't know how long the battery will last. They were all turned on when I received them. Well worth the money.

Accurate!

All of them are within a few degrees and humidity is also on point

Cheap and accurate

These hygrometers are small and accurate.I have had them for about 15 days,I Test their temperature and humidity In different environments. These test show the error is between ±2℉,±5%RH，as the seller described.And what I am most satisfied with is the price,$19.99/12pack,about $1.66/pack,I can not find Lower prices on amazon.Thanks the seller.

Great value!

Great value, I wish the temperature was larger than the humidity reading but still a great product I have it on the dashboard of my truck

What incredible value!!

I raise worms, crickets, etc - temperature and humidity are equally important to me; I bought twelve so I could put one in each nesting box. I totally love them. All twelve in one box were within 3% humidity range and 5.1° F temperature range — sweet!!!

Accuracy and cheap

Sometimes simplicity is best.I just want temperature and humidity and these provide.Extremely consistent from unit to unit. Very cheap and quality is good,I recommend them.

Good value

They were all within 2% of each other very nice.

Works great!

I manage a storage facility and use these to monitor the climate control buildings and they work great!
