The best thing about this product was its ease of use; everything from entering data into formulas via drop down menus right up until final submission. I found most aspects easy enough but there were one or two things which could be improved upon (such as creating templates). Overall though very good value at around £15 per month! There's nothing really bad in particular regarding functionality so far- however if using cloud technology with multiple users/companies then having an offline version would probably help improve user experience slightly?
