## Customer Reviews

### ⭐⭐⭐⭐⭐ Good product
*by T***A on 6 November 2022*

It gives accurate temperature readings

### ⭐⭐⭐⭐⭐ Works well
*by L***E on 4 June 2023*

Bought this to replace one I had free around 14 years ago.Works well.

### ⭐⭐⭐ Can't read it
*by A***R on 20 May 2020*

The display is impossible to read. The colours on the backing board are good and the details printed such as "too hot" or "too cold" are very helpful, especially for the elderly relative it was bought for. But the display is very small and too faint to read.
