Easy and Simple to use but always tries to trick me into using the Premium Services with automaticly checked boxes, confusing wording, and features that trigger the Premium Service without clarifying the reason they were triggered. Every year, I'll click and skip every attempt to get me to sign up for their Premium Service and every year I'll end up with some Premium Service tagged on that I have to go back into my filing and figure out what benign button I clicked to trigger a random ridiculous charge.
The website is always user friendly and helpful. I have been using Turbo Tax for more than a decade. I always refer friends and family to use it as well.
