I like how it's easy to use! It helps me keep track of all my contacts' information in one place which makes organizing events or collaborating with colleagues easier than ever before (also since its free!).
The interface could be better organized so that certain tasks are accessible from anywhere without having have go through several screens just find what you're looking fo - but this isn't really an issue as everything else about helloME has been fantastic thus far!! If your thinking "what if i lose access" there may well not even need too worry because their entire platform will still work perfectly fine when they do close down/go outta business etc.
