The best thing is that it's very easy to use compared with other products available in market! We've been using this product since last year but we have never faced any issues or problems so far as such was not addressed by their customer support team either!! So I would say everything looks good from both points of view - Easy integration (even though you need some technical experience) & Support/Customer service department are really great too :) Have used few different tools like Tableau / Qlikview etc., which were difficult time taking at first due to lack of proper documentation around them.
But once figured out how does things work behind scenes they became super user friendly even without much training required ;).
