Yes, I agree. I wouldn't use it even for that! Wix was designed to be simple for beginners, but it's a disaster for going beyond the basics.
The huge marketing spend behind Wix, plus the slick free site builder, should have given you a great experience right from the outset. But instead, the site builder is bloated and opaque, the images don't load properly and Wix's drag-and-drop design elements are uninspired. Wix is too simplistic to take on the big boys, but it's as user-friendly and responsive as the next-best site builder.
