I like that it is user friendly for patients who are not computer savvy or don't have any idea what they're doing with computers in general! It's very easy once you get used too - so if someone isn’t tech savy this would be great option because there aren'r many other options out their as well!! Sometimes when clicking links within emails from qwai health (or just normal websites) some programs will crash my internet explorer but usually only happens one time during browsing session until i close down IE completely then reopen browser again which fixes problem sometimes.
