I like that it's easy enough so new people can use them without needing training from an existing user of this system (that would be me). The interface could probably do better at making more intuitive selections when they aren't straight forward choices - but then again maybe there are other systems out their where you have less options? As mentioned above though if your looking into genetic testing/testing than its great! It really helps give insights towards what diseases or disorders someone may possibly suffer too which makes things easier down-the road once diagnosis has been made by doctors etc..
