### ⭐⭐⭐⭐⭐ Training Master!
*by C***K on May 5, 2026*

Absolute game changer in training new employees on the phones. Easy to use, and works perfectly.

### ⭐⭐⭐⭐ Labeling Issues
*by H***N on September 25, 2018*

This product operates as advertise, but there is a confusing aspect to the the unit that I bought. When going to use the unit the label for the mute for each line is backwards. The label says that commute a line the operator is to push in the button. This is incorrect. To operate the line and question, the user must have the corresponding button pushed in. At first I thought my model was defective, but now I understand the labeling was incorrect. I even went so far as to initiate a return, but then I found out the mistake. That is why I rated this at 4 instead of 5 stars.
