This was a replacement for a lesser model I had purchased from the same vendor. I went through two and both were basically DOA. The company, excellent to work with, offered me this upgrade for the trouble. So far it has worked well. Decent start up time and good task handling. I only needed a basic unit to run speaker building software tat I couldn’t get for my Mac. It also has USB inputs for my DATS testing tool. It’ll work for me fine.
