The ease of use, it's quick response time when dealing with issues as well excellent customer service! Nothing really but if you are looking for best in class software this is definitely worth checking out!! I highly recommend using their API to integrate into other systems like our SCADA system (PEMS). We've been able solve many problems related backflow prevention by leveraging data collected through vapar cameras which have now become essential tools within my department at work due diligence efforts regarding pipeline integrity / risk management/ safety etc..
