I like that we have been able to use this software for so long now without any issues at all! It's very easy to create new patient profiles & check their progress throughout treatment. The only thing i don't really enjoy about it are its cost (as in most things) but if you're looking into an EHR system then there aren't many affordable options out there - however, they do offer discounts when paying yearly rather than monthly which makes them more attractive :) We've never had problems using evolution or encountered errors while creating accounts/billing etc., everything runs smoothly from setting up the initial profile till billing the client after completion of treatments.
