Rated 5 out of 5Â by HDShopper Clear display, appears to work good
I purchased this for a music room to ensure proper humidity levels for guitars. It took about 10 minutes to adjust to the room. I almost returned it at first because the temperature appeared stuck on 81 degrees. However, after about 10 minutes the temperature was dead on, based on my IR thermometer. I have no method to assess the accuracy of the hygrometer, but based on other's reviews, I expect it be accurate. If I move it into the a/c vent air path, the humidity drops quickly, so it appears to have good sensitivity and responsiveness. I care about the humidity, not the temperature, so the fact that larger first number is the humidity and not the temperature is perfect for my use. I will likely purchase another one to take traveling in my guitar case. I just purchased this today, so I cannot comment on long term quality, but out of the box, I have no complaints. It does not have a back-light, but then I have no need to read it in the dark. The high/low record resets automatically every 24 hours based on the time of day you installed the battery.

Rated 4 out of 5Â by Jason Great, fairly accurate, monitor
The monitor has a very clear display which can be easily viewed at any distance or angle. It has a button on the back to display the temperature in either Celsius or in Fahrenheit. It also has a clip-on with a magnetic strip attached on the back which can also be turned into a stand to place the monitor in almost any part of your home.
Although there is no way to calibrate the monitor, the temperature and humidity readings are fairly accurate. Compared to 2 other thermometers and tested with a hygrometer calibration kit for relative humidity, the readings were accurate most of the time but can occasionally be off by as much as 2 degrees Fahrenheit or 2% RH.
Since I have only owned the product for a week, I can't say how durable the product is and if the readings can still be accurate in the long run. It does include a 1 year warranty but according to the manual, you must register the product online to be eligible for the warranty.

Rated 5 out of 5Â by Adam Great product!
Totally accurate. Bought 2 of these and they read the same. And are very accurate to more expensive hydrometers. Also bought a Danby dehumidifier and the Temp and Humidity readings are very accurate together. Great product!

The hygrometer function in the unit I purchased is grossly inaccurate. The RH readiings were were off by -14 percent when compared with a properly calibrated professional quallity unit ( and also confirmed by the "salt test "). Other inexpensive units that I have previously purchased have been within <+-5% . BTW, these units were dispaled outside in the "greenhouse" area of my local HD store. Maybe these conditions aren't the best for the sensors. I returned the unit and will look for another brand .

Rated 3 out of 5Â by Mike5M Not bad for price.
When I purchased the product it seemed very good i. e. accurate ., but it did not
reset highs and lows.
I took it back and exchanged it for another and had the same problem.
I don't know if will keep it or not.
