I just started using this plugin for a site I'm developing. I had a minor glitch and I wrote the developer about it. James responded back within an hour with detailed questions about my problem. He then looked into the issue and resolved my issue and posted a revised version of the plugin all in a couple of days. The plugin functions perfectly now and is a very elegant solution to the complex problem of switching themes based on a desktop or mobile environment. I couldn't recommend this plugin more highly.
