The software works and has met my needs. I found what appeared to me to be an error in the results once. I find much of the help text to not be very helpful. I usually have to go to the IRS documents if I need to figure something out. I keep using it because I'm used to it and don't know that another product would be any better
Generally very good if you are operating within its limits - which most people do. Last year I did hit a difficult situation due to too many stock transactions than the software could handle - but most people will not hit it.
