Thrilled with results

Added this to my site over the weekend. Went from PageSpeed and YSlow scores of D, to A and 100% for both. Site went from loading 7.8 sec to 1.7 sec, despite lots of javascript, tracking, and pixels. Very happy with results. Also happy with developer support, as they were responding to me over the weekend (off hours) and helped me dial in my settings to get it optimized for my site.
