## Lineman's Reference - URD Reviews in United States

### ***** "Must get for apprentices."
Both the overhead transformer app and the URD app have helped me significantly in learning the trade. No reason for any apprentice to not get these apps and learn their trade.
-- Abyrne96a, 2025-01-23

### *---- "Bug?"
It won’t let me move anything with a shot gun stick. I feel as there’s a glitch when trying to grab objects with your shot gun stick
-- Hdjesbna, 2024-11-27

### *---- "App does not work"
The app stays stuck on an ad every time I open it
