Pros
None I can actually think off. The benefits are not that great as they highly taxed.
Cons
Their core values of being a "trusted partner" is a joke. They deliberately lie to their customers on a regular basis. They have zero integrity. They love hiding behind their Terms of Use. Which allows them to say one thing to customers and do another. As a result the customer has no come back. Lying to customers about the the future viability of some products such as ICMLive and IWLive. Those products are dead in reality. Constant changing of the goal post to their customers and treating them with contempt. For example their cloud simulation technology feature that us available in InfoWorks ICM & InfoWorks WS Pro and InfoWater Pro. Were sold as as unlimited simulatanous usage. However in reality there was a hard cap of 40,000 simulation minutesn (or 667 hours). However this has been reduced to 100 hours and 50 hours. Unless you are a lucky few who managed to get an exemption such as Scottish Water, Acardis and Aecom.
