The team has really done wonders for us! They have implemented several new features to our system within days which was not possible before due to time constraints etc., Their customer service is excellent as well - they are very responsive and always available when we need them, even outside office hours.
Nothing so far but will update if there's anything else I should know about this product or their work process / methodology. It took less than 2 weeks from start till final implementation phase (including training).
