Review: Great Accurate Product - Great product. Works wonderful for my PLA and PETG filament storage keeping them at 10% Humidity. Accurate, easy to see and no issues. All 6 are in different containers and they all show same results. Love it. Great price for the value.
Review: Very accurate right out of the box - Alright, so a lot of people have written reviews for these little hygrometers and it doesn’t seem that a good majority of folks are using these for their cigar humidors. I’ll go ahead and let folks know that I bought the specifically for my desktop humidor. And I want to say that that so far in the week or so I’ve had these units. They seem to be working perfectly. First thing I did was do a humidity test and calibration using a BOVEDA calibration kit see picture below. These two little hygrometers consistently read at 75% to 76% humidity, which was right on par with what the test was. So for me, at least these units came as close to perfectly calibrated as possible right out of the box. They’re small easy to read and do the trick. Personally, I think there’s no need to go out there and buy a fancy expensive one unless that’s what you want. These two just fine for cigar humidors, and for telling the humidity wherever you may need it. Please keep in mind this is for me and my experience only your mileage may vary.

## Questions & Answers

**Q: Has anyone used it for a while? good quality? And I want to use it to test the data of my new dehumidifier, thank you.**
A: I have used this hygrometer for 1 year and it works great. living the south, I aslo have a dehumidifier. I need it indicate whether I should turn on dehumidifier. It works great with the dehumidifier. 
Also, if you also need a dehumidifier, I will recommend this mylinskin brand, search for 'Mylinskin dehumidifier'.

**Q: Is it water proof? Want to use it in my snakes terrarium but not sure if it will handle when it gets misted**
A: It should be fine for in your snake’s terrarium as long as it’s not submerged. I use these for my crested gecko’s terrarium and I’ve misted straight onto this device and it’s totally fine. Obviously the humidity will go up quickly when you spray directly onto it but The device itself will be completely fine

**Q: What is the process of calibrating this gauge?**
A: There is no calibration. Only  Celsius and Fahrenheit switch

**Q: Can i use this for my cigars?**
A: Yes!  They are small but accurate and will easily fit in a humidor.
