## Customer Reviews

### ⭐ Worthless
*by L***N on March 8, 2022*

This was horrible from the start. You can't read the numbers; the display is messed up. It also looks like I received a used item as the black strip with the display & Sentry symbol are scratched up.

### ⭐ This calculator arrived very nicely packaged, however
*by R***K on August 20, 2015*

This calculator arrived very nicely packaged, however, it does not work. Only half or less of the numbers will even light up. I have purchased several others of these and they work well, however, this one is useless.

### ⭐ Callaror no good

Machine no good
