## Customer Reviews

### ⭐⭐⭐⭐⭐ Great little phone
*by L***W on December 10, 2025*

A nice upgrade from the older phone. Very easy to use for someone who wants something simple.

### ⭐⭐⭐⭐⭐ Great phone, works as it should.
*by M***E on November 27, 2025*

It took an extra day or 2 to arrive but it works great. My mom only does flip phones and I'm glad we can still buy them!

### ⭐ Went bad after only one month
*by R***V on November 24, 2025*

Started off as a nice phone for the money. Worked great. However, after a month, just outside of the return period, ring speaker stopped working, so now i can't hear the ringtone. Additionally, battery life is terrible. The phone runs out of battery without any use. All additional radio channels are disabled (wifi, BT) and background data is off, but it doesn't help. Very disappointing.
