Jake Watkins

Since I started training a few months ago, I can see there’s been a huge difference in how much more efficiently and effectively I can handle PLC repairs in the field. Our clients are telling management how happy they are to get back online more quickly and save money because I’m turning around faster fixes. I definitely recommend it for anyone who needs PLC training at any level.

Mario Flores

I needed to get up to speed on working with Siemens PLC equipment and came across RealPars training on YouTube. I watched my first video and immediately went to the website and signed up as a student. I like the way information is explained step-by-step and that it’s broken down into small chunks…I can go back and review anytime I want. I’m already seeing that I can perform repairs faster and with more confidence. Three of my co-workers were so impressed, they signed up for RealPars, too.
