Uneven user interface - sometimes its pop up windows, sometimes its advance buttons on bottom of screens, which are often too long and require a good deal of panning downwards. Unpleasant error checking -- sometimes leaves you back in the program requiring manual return to correct stage in program. Help screens aren't particularly helpful.
Very easy to use. It covers and handles well all tax matters that are relevant to me. I have been using H&R Block software for my tax returns for many years now .
