I like that it looks at different areas such as SQL statements, slow queries etc..
It's very user friendly with easy navigation around each area which makes troubleshooting much easier than in other tools where there are more steps between getting an error report or seeing what query takes most time for example! There could be some improvements but overall this tool does exactly we need - fast reporting about our database status so far every day without any problems (SQL-side). We needed something quick way how see general DB state daily/weekly rather then manual checking everything by ourselves after few hours later when server was down again from DDoS attacks /etc... If anyone needs just one point why they should try Pg Dash first because if all goes good even better features will come soon ;) At least now its really simple to use compared next generation competitors outthere :).
