I like that it is easy for any business owner, who has no coding experience at all (or very little) to use this tool without needing IT help! The support team are always willing to answer questions as quickly as possible which makes working through issues much easier than if we were dealing directly with another developer's code base.
There isn't anything i dislike about using geo sensor so far but there may well come along time when something does get missed out. We have been able to create customised pages/forms where only users from certain regions will see content they should not otherwise access.
