Likes:They all worked right out of the box.Didn't have to buy or install batteries.Since I recieved five I tried them all around the house, took reading, then switched them and they where accurate to +-1% humidity, +- 0.2°CThey are made to clip in a cut out which can mounted anywhere.Very good contrast, meaning the display is easily readable.Cons:The are made cheap.That being said. They feel cheap but don't look that cheap, I'm very happy they all work and pretty accurate.

A cheap, easy effective way of monitoring humidity in a large basement.Can monitor humidity and temperature using remote wifi camera

I highly recommend these for a number of reasons:- they do what you expect them to- very easy to read- accuracy is not perfect but only ever off by 1-2 % and/or degrees- the price is pretty sweetI can see why a few things may be considered cons:- depending on the use, 100% accuracy is absolutely required- batteries come already installed (at first I was not a fan of this but considering the battery type and what it is powering, this isn’t an issue because they will last a very long time)Overall, I am pleased with this purchase and highly recommend! I use these to keep track of the temp and humidity of my bearded dragon’s enclosure, as well as the containers I use to breed his live feeders. For these purposes, the accuracy of the readings can withstand such a small margin of error as long as I remain safely within my ranges.

I've been using these for 10 months with the original batteries and I like them. No hassle, easy to read, and accurate enough for my purposes. I'll probably buy more just to leave them laying around in different places. The only issue I've had is the temperature can occasionally 'stick' at some value and won't change. This can be fixed by taking out the batteries and putting them back, but it can be hard to notice right away. Because they're so small and so economical, I'd say a good option for more important measurements is to use two, and make sure they agree.
