Muy buena relación en calidad precio para quienes comenzamos con la parte de electricidad

### ⭐⭐⭐⭐ Not perfect but really cheap
*by J***. on September 22, 2021*

It does not display the output voltage when measuring (like other meeters do). It is a good troubleshooting indication to also display the voltage

### ⭐⭐⭐⭐⭐ Work as intended, good quality, easy to use.
*by J***Z on July 23, 2024*

Good product, very good price.
