I like that we can get detailed information about our users from all over Europe without having expensive software or staff in multiple offices around Ireland, UK etc! The support team is very friendly too which makes working together so much easier than other tools out there at this price point - it has been great for us since day 1 when starting up business here many years ago now!! Nothing really but maybe if you are looking into more advanced reporting functionality then perhaps consider going through some free trials first? We use insight whale mainly because its extremely simple compared most others (ease-of implementation) & also saves time by not needing an agent/support person everytime anything changes within GA account / profile settings meaning less work overall!
