Followup Review. The independent truth about these. There still great!
I was looking for Humidity Sensor devices a 4 pack cheap from this manufacturer. They are just basic. Current Temperature and Humidity only. No magnetic attach to metal. But they work great. Temperature within 1 degree Fahrenheit. Same very close for Celsius. I have all 4 running. Has an actual on/off switch. Humidity accurate within 2%. They tend to read on the low side 1 to 2%. I am comparing this to 2 other brands. Comes with my favorite battery installed. Lithium coin CR2032. But you will need a very small Philips screwdriver to change it. But I have yet to have to change a battery after nearly 4 years of using portable humidity devices. However a caution. These ALL brands simple LCD screens will ruin if it lays flat for a while when it is powered on. So use the built in flip out stand. Does not have a built in magnet. They provide some stick on pieces. But it is better to have ALL brands standing up for accuracy.These are a GREAT value. Just quickly press the button on the back to switch between Fahrenheit and Celsius. Monitoring different areas and changing humidity with dehumidifiers has greatly improved my life.Five Star. My 2nd Review of these after having used various brands of these for 4 years. This is the best deal and accuracy for any current read temperature and humidity monitor. Seriously. I have been using them for the past few months. Accurate for Temp and humidity. Agrees with other good brands and models. But needs a little physical space gap. So not magnet for your refrigerator on these. Even the higher end stuff requires a 1/2 inch space to read accurately. High end stuff also reads lows and highs accurately. Not worth the money for more than one. It pays to have multiple temp/humidity monitors in your home. You will see how it can vary room by room. Even apartments.I have a good dehumidifier to remove the humidity to a comfortable level. Combined these sensors and dehumidifiers have transformed my life. These sensors tell me if the dehumidifier is doing the job or if I need to adjust the settings on the dehumidifier. These sensors com with a replaceable CR2032 coin lithium battery. Probably last at least 3 years.Highly recommend . Found to be more accurate than my 1st review.Just my opinion here. I am not paid or compensated to write any reviews.

Helpful Devices for comfort and saves money
Wonderful and Handy temporture monitors especially in this extreme heat. They help us monitor and control the heat all over the house. This keeps us from running up the electrical bills.

Whatâs the temp?
They are pretty accurate. Batteries died in two of mine pretty fast though.

Excellent, accurate product, useful to keep track of all corners of your home
I love these mini hygrometers! I have purchased 8 total units so far. They appear to be very accurate. They are all reporting within a few % humidity of eachother, and nearly identical temperature. The humidity reading closely matches my expensive de-humidifier reading which uses a high-end hygrometer. And these little hygrometers were the reason I knew that we should invest in the de-humidifer. They help me feel comfortable knowing that all corners of our house are within safe humidity ranges. Out of the 8 purchased, I did receive one unit that wasn’t outputting accurate measurements so the company gave a generous partial refund. Would order these again!

Small and unobtrusive
Small and unobtrusive that can stick on the wall. I was surprised that the humidity level differs so much from room to room. I needed a humidifier in the winter. When it began to signal that it was no longer needed, I bought the 4 pack so that i could check the level in 4 different rooms located near or far from the humidifier. I was surprised that all are normal to high, but vary quite a bit.

spend a few bucks extra on other brands.
Why did you pick this product vs others?:They were cheap. And I got what I paid for. 3 of the 4 had a dead battery on arrival. Humidity is accurate, but the temp reads ~4 degrees higher than actual. As long as you know how to interpret the data, they may work for you. Be advised, there is no magnet in the case.

Work well.
Tiny, no bigger than a book of matches. Got one with a dead battery, but the company will send you a replacement if needed. I happen to have some spare batteries and changed it my self. Now, donât know if itâs the product itâs self or the spare batteries I had but the batteries donât last that long.
