So I believe I have been using this app., for a little over a week now, and so far it seems to be working just fine. It hasn't slowed down my page or anything. I truly like it. It does what it says.
Very easy to use to install GetSiteControl. We don't have a developer on staff and this saved us the hassle of hiring one of our contractors to do this. The $5 was well worth the 1-hour charge we would have received from a developer.
Love GetSiteControl. It's an amazing tool for on-site modals & pop-ups with detailed behavior targeting.
