We have been using them for our BI reporting needs since 2013, they are very professional in their approach to solving business problems with data analytics tools like Power Bi or QlikView etc., there is nothing much that I dislike about this product from my experience so far as it has served us well over time without any major issues of downtime/performance degradation during peak hours (or even non-peak times). They also provide excellent customer support services which we appreciate highly! Nothing specific but would love more customization options available if you want something custom built rather than just use ready made templates provided by bigbisolutions.com - please do try out your best not only price wise but other features too before deciding whether its worth paying premium rates compared to many free alternatives online today. Our organization uses these products extensively across multiple departments within one particular division at work place hence ensuring seamless flow among all users.
