## Description

Product description

Review: Quality product - These worked great for our greenhouse this spring! Easy to set up, install, use, and read! Great product for the price.
Review: Perfect for snail, and other smaller critter habitats! - I bought this 2-pack for our Grove snail habitat, and they are exactly what I needed. They arrived ready to go and were working perfectly right out of the box. I really appreciated that they came with extra batteries and extra sticky dots—it made mounting them inside the enclosure so much easier! They are small enough that they don't take up much space, but the display is easy to read. It’s great for keeping a close eye on the temperature and humidity levels to keep the snails happy. Excellent value for the price!

### ⭐⭐⭐⭐⭐ Perfect size and work great
*by P***Y on March 6, 2026*

Perfect size for me and my use. I got these for my isopod bins and they are very helpful. It helped me figure out that my humidity is a little too high and my temperature is perfect :) It came with batteries in them already and an extra battery for each hygrometer. It also came with a large foam sticker, but I opted for a small glue dot so I can easily view the reading.
