I have had Mitchell for most of my automotive career 30 years. It was good before snap on bought them and took over. No i can honesty say it is worthless!! It takes forever to find anything. I have contacted our rep and he made an appt to come out and show use how to use the system. He canceled the appt and i never heard from him again. It is faster to call them and give them the information your looking for and let them figure it out. Would not recommend pro demand to anyone.
