I've built quite a few website with it. I've had similar experiences to the commenter that John linked to. Overall, I find I'm building website much faster with it. I've also used it to build a framework then exported the code and integrated it with Wordpress. I do wish they had a gallery style component, similar to advanced custom field's gallery plug in. I'm sure they'll get to it eventually. My website was built using webflow: http://nathanielperales.com
