### ⭐⭐⭐⭐⭐ What I like about this new wall clock
*by G***G on December 5, 2025*

### ⭐⭐⭐⭐⭐ Great clock!

### ⭐⭐⭐⭐⭐ Good clock!
*by M***3 on July 17, 2024*

We love this clock! It was working great until a cat jumped on our mantle and knocked it down. I don't know what's wrong with it now, some of the numbers don't fully light up and we can't figure out how to change the time. I've changed batteries and messed with it for a long time until I realized I can't fix it. I don't have the heart to throw it away cause it still tells time, the wrong time but it does work. The size is great! I plan on buying another one soon to replace this one but just haven't yet. The temperature seems reliable, and it's very easy to read from across the room!
