The GUI of this tool is very easy to use as well as efficient. I am able to produce different types of graphs, charts, tables etc. within few clicks without having any prior experience or expertise about BI tools like Microsoft PowerBI. This software doesn't have a trial version which can be downloaded by anyone who wants to evaluate its quality before purchasing it. So if someone wants to try out this product then I suggest them not to do so until they are fully satisfied after using this software at least once. We were searching for an affordable BI solution but didn’t want to invest heavily into building our own one. Also wanted something simple yet powerful enough to handle large amounts of data. After using biuer we realized that nothing else compared to their simplicity & price range. Ease of use, excellent support team and good interface. Some things could be easier such as copy/paste from one table or page to another but it's not a big deal. No issues so far! We're solving real world problems by analyzing customer behavior using BI tools like Biuwser.
