Display too small
Readings are good but I wish the numbers were bigger on the screen. Hard to read from a distance.

Accurate and Small
Works great in my baby's room. Very precise readings compared to my old thermometer. The app integration is seamless.

Perfect for greenhouses
I use this in my indoor plant setup. Love the history tracking feature to monitor changes over the week.
