After reading many reviews and comments on this plugin, I was a bit nervous to add this to a client site, but after testing on two other dev sites, without issue, I'm almost convinced that this plugin is solid. I was looking for something to create a custom user role and limit access for that role to just one custom post type. This plugin did just that, but I had a tough time figuring out just how to do that. So for now, the 5-stars hold, and so does the plugin. My fingers are crossed.
