I absolutely love this system. I can't say enough about it. It's my favorite calculator available. There's lots of them out there. This one is the most user friendly and the quickest to learn.
Sometimes this whole thing can get a bit mind? boggling! This website is easy to use and understand.
I have added the recommended version and I will tell you, it is SO nice to have. I have added everything my family uses so it is easy to keep track of what we need and what we already have.
