### ⭐ 







  
  
    Great tool for antique phones.
  

*by A***R on Reviewed in the United States 🇺🇸 on 21 February 2020*

Seems like a good product for occasional humidity/temperature readings if you are monitoring an area over a period of time.Unfortunately, unless you are still using an Android phone from 2013, the item and companion app are useless.How about an updated app for Android? Or at least state explicitly in the description that it will not work with newer phones?

### ⭐⭐⭐⭐⭐ 







  
  
    Technicians humidity tester
  

*by B***E on Reviewed in the United States 🇺🇸 on 1 March 2020*

Great humidity tester with a nicely concocted smart phone app. Useful, compact and priced right.

### ⭐⭐⭐ 







  
  
    It's a bit oversold
  

*by J***T on Reviewed in the United States 🇺🇸 on 1 March 2019*

I think this is oversold - reading the ad copy makes quite a few claims about finding leaks and such, but this is too simple of a tool for such work.  It's a hygrometer.  It will tell you the relative humidity as well as a few calculations, but that's really about it.  For continuous monitoring inside a humidor, this would be good if not overkill...but in sum, this is about it.Used for what it is, I have no complaints.  I will say that I don't generally trust out-of-the-box calibrations for hygrometers, though calibrating this is a bit of a pain in the tookus owing that it needs to be plugged into a device to work.  So no leaving it in a known-humidity environment for a few hours (or days) is a bit of a non starter.  Response time to changes is not bad, but not stellar either - about as expected.Then, if you don't have a headphone jack on the phone (iPhone X here....) an adapter is required.The app is straightforward and does lay out the information in a simple and focused way, but again...the data being analyzed here isn't that voluminous.  It's not a miracle device.  It will give you a second data point (or a first) if you want to measure localized humidity.  No more, no less.  Good for what it is, but between the price and the promises I'm not over the moon with it.
