It is easy to use for my practice! Very user friendly interface & very responsive support team when needed!! Nothing at this time - it's great so far. I will say however there are some features missing from their platform like being able to export your reports into other software packages such as EMR or Practice Management Software but overall we're happy with our decision of choosing MOgo over all others out there (iCloud etc). We have been using MoGo since early 2016 now-we've not had any issues yet which has led me believe they were working hard towards improving things/add new functionality constantly without letting us down too much by way of bugs / errors within system itself!
