This is an excellent plugin that saves you tremendous of time from integrating WordPress with box.com. The code is very well written which allows you to utilize the core functions for more dynamic integration with Box functionality should you wish. The key features are well documented and allow you to create file managers, file upload/download areas, direct link to Box documents and embedded documents via links as well. You can also manually assign a root directory to every user which creates a substructure the user cannot escape. Very useful if you use Box in a repeatable fashion, i e every user has a similar directory structure. There is also a possibility to create a user's folder structure automatically and prefill it with some default content, which I haven't tried though. The product also contain a very intuitive shortcode builder to deploy the functionality in all posts, pages, text widgets etc. I have so far not experienced anything but good performance. And the support is actually six-star, based on what you can expect from something at this price level. This really extends my functionality and has proven to be exactly what I was looking for. Very satisfied.

Not great, riddled with issues. Yuk

We purchased the plugin, and yes we did have a minor bug but so what, sometimes bugs do happen, what is important is how the developer handles the issue and I have to say Floris has been nothing short of amazing in fixing the issues. This plugin now works like a champ and we are 100% satisfied with the software and the service! Keep up the good work!
