The best thing about this app is that it gives us information regarding our target audience which helps me plan my marketing campaign accordingly. I can also see where people are from different countries or regions using IP addresses so as per your requirement you will get more customers for sure. It takes time before we start getting good results but once started there's no looking back. We haven't found anything negative at all from their services yet. Try them out! They have helped increase engagement of our website visitors through push notification campaigns.
