I am a home cheese and sausage maker and I bought this mainly to monitor the temperature and humidity of my cheese/sausage aging cabinet. Other than that I use it for general home measurement purposes too. After a year of ownership, I can say it is an over all average performing device with some design flaws.

Pros:
-Price: It is pretty cheap for what it offers. I paid it less than $10 which makes it relatively cheaper compared to similar devices.

-Multifunctional: Not only it shows the temperature and humidity, but also it displays the 24 max/min observations for each category as well as an overall comfort index which it basically calculates taking the humidity and temperature values at a given time.

-Ease of use: All what it displays is in one big screen so you don't need to switch between functions. All you need is a glimpse and you get the whole information it offer. It only has one button and that serves for the purpose of switching between Celcius and fahrenheit which one only rarely would need.

-Stands humid conditions well: For the purpose of cheese making, I sometimes need a relative humidity of over 90% at 55F and that requires cooling as well as continuously humidifying the air. That device has so long stood well against consistent high humidity which had caused some problems with my previous digital device (electrical devices do not like water.)

Cons:

-No background illumination: This may be annoying when you put it in dark cabinets. I would prefer a button that would give some light when needed.

-Not great material quality: The fridge magnet came broken out of the case, yet I did not bother much. Apart from that, the upright positioning part feels flimsy that may go anytime

-Is not 100% accurate: Sometimes I test this and another humidity temperature monitor in my wine cooler that has a temperature screen. The other one matches the screen reading better than this one but in the end this is not way off the scale too. (only a fahrenheit difference or so.)

-It is not sensitive at all: This is the major drawback of this device. The temperature readings are with two degree increments. For example you see 75F and 77F but you never see 76F. This is totally unacceptable for someone who is after strict measurements especially when I see devices that can measure up to 1/10th of a degree difference and costing only a little higher than this one. My other device that I bought abroad can do that and therefore I use it rather than this one when the exact temperature reading really matters

In conclusion: If you are not making an experiment or really obsessed with the exact readings, this device can meet your expectations in routine daily use. However there are some instances that you really need to know what exactly is going on and there you need something smarter...
