The Honest Reviewer –
Excellent, inexpensive temperature & humidity gauges.
We were looking for something cheap to monitor the temperature and humidity in various rooms of our house. These fit the bill – four gauges for less than $10.My video shows them immediately after we unbox them, But we’ve been using them for a few weeks now and I do believe that they are accurate.They are small enough that we can have them just laying on a counter or a shelf or if we wanted to mount them, we could do so easily and they would be visually unobtrusive.If you need more then temperature and humidity then you’ll want to look elsewhere but for those two readings, these work.

Good for Monitoring Temperature and Humidity Trends
My 10 year old glass thermometer fell out of the window and broke, so I decided to try a digital thermometer this time around. The LCD display is so much easier to read! For less than 10 bucks, I think this four pack of hygrometer/thermometers is an excellent value.These gauges are fantastic for monitoring general humidity and temperature trends. However, if you need pinpoint accuracy for something critical, like a reptile tank, they might not be precise enough. I’ve placed one in my closet to keep a close eye on moisture levels. If the humidity climbs too high, I know it’s time to refresh the desiccant to keep my clothes in good condition.I do wish these gauges had a backlit display because it would expand their usefulness at night. Nevertheless, they work well for my purposes, whether placed in a window or for monitoring temperatures in various rooms of my house. The original LR44 batteries are easily accessible and replaceable when needed. Plus, you can affix them to walls, windows, car dashboards, and more simply by applying a strip of double-sided tape to the back.
