I like that it's easy for us in sales at this time by using analytics we are able make better decisions when making deals with clients which helps them get more business out off me! It really has not been an issue yet but if there were any issues they would know about soon after launch since everyone will use their service so quickly!! There isn't anything i dislike right now other than maybe how new people might feel overwhelmed trying something different or learning what you need to do first before getting into actual metrics etc..
try giving yourself some extra time once installing/using quantum metric because sometimes things take longer then expected (especially during initial set up). We've had great success increasing conversions while also seeing increase revenue overall within client accounts through monitoring data collected via QMmetrics.
