Very straight forward. Works perfectly

So easy! Just activate, and then the option for Google Experiments code appears on each page. So easy to get going. (As long as your theme is supported).

Would ideally like the option of excluding WP administrators from being in the experiment. Because after I launch an experiment, if Google sends me to one of the variations, I can no longer view the original page! Even in WP preview mode. My work around is to temporarily untick the “Google Experiments original page” checkbox, view the page, and then turn the checkbox back on.
