Review: Perfect for parents! - Why did you choose this product over others?: I can’t recommend this product enough, it’s smaller than I expected but it does its job perfectly and I find it really accurate. Bought this as a first time mum to keep an eye on our bedroom temperature and it’s great, the display is constant so you don’t have to switch it on and off. I found it took about an hour or so to fully acclimate to the room temperature when I very first switched it on, but since then it’s been on permanently giving really accurate readings. Will be buying more for our other rooms.
Review: Great little product. Very pleased. - My son has aggravated vocal chords, so change in temperature and weather means he loses his voice often. After doctors and specialist appointments we are told humidity or dry air in the house can impact him massively and to ensure a steady constancy in his room at night. So we brought this little gem to help us monitor things more closely. Small and not imposing, it was really easy to setup with loads of ways to install. Comes with a little stand if you would prefer it not to be mounted on a wall, as well as sticky dots for a wall and magnetic sticky pads too. Batteries are supplied and the display is super clear and great quality. Displays the temperature of the room and humidity perfectly (compared against our next thermostat in the same room for accuracy). Temperature can be changed using the button on the back to either °F or °C . Great little device and good value for money.

### ⭐⭐⭐⭐ Nice, accurate little thermometer/hygrometer
*by G***R on 15 July 2025*

Accurate as measured against other devices. Only reservation is that it is very small, but LCD figures are big and bold. Smiley face which appraises the humidity reading is harder to see. But the figures speak for themselves: 70+% is high. Face smiles for anything in the 50s and 60s.
