I like how easy it was to learn with this program as well being able to use all my experience working within an electrical power plant environment which helped me understand what needed doing when using this tool. Nothing really! It's very user friendly if there are any questions feel free ask us at Powerhouse Electric we will be more than happy to assist!! We have been solving problems such has safety critical issues where people were not trained properly so they could operate equipment safely without putting themselves into harm’s way.
