You really will catch on to the user interface quickly. I do need to look at YouTube videos sometimes to understand how to do things such as setting up email alerts, etc. When this happens it's a 2 minute view and then I get it.
I want a computer that I know, no matter what will always function as expected. Even when there are power outages or whatever. My Profilux has been running for almost 3 years and never, ever malfunctioned in any way. It is in the cabinet with the sump, skimmer and all that other stuff (hostile environment).
