I supported a couple of clients who both had started constructing a site on their own and got stuck. The widgets only get you so far, no problem - cleaned it up for them my bigger issue is portability of their code. It's all proprietary - want to get locked in and either stay with Wix forever or re-do your site? The Wix is for you? Hate writing pure HTML/CSS and love bloated code? Come on down! Oh, and customer service on a paid plan? Does a day or two later work for you? Do you hate reaching a CSR right away to get your issue resolved? Wix is for you.
Still feeling lucky? Google Wix and autobill...
Sadly, on the surface - the concept of Wix is good but it is poorly executed. Even with the horrible billing aside, bad customer service overlooked and the bloated code - the lack of portability of your pages should be a red flag.
