Questions about Exit Splash

Hi there all

Is anyone out here using exit splash? Do you see any conversions from the redirected traffic?

Also, will installing this script on your web page affect your SERP ranking? I have heard that any sort of script that does not allow the user to leave a web page is usually frowned upon by the Google bot.

Any experiences of something similar or is it all right to install. I could not really find a free version on this forum but I will buy it if it is wort it. Would be glad to hear some opinions though.

Thanks
