My daughter was thrilled when she got this to use.  She is always trying to learn math above her 7-year-old level and this is great for that because it allows you to adjust the difficulty.  Love how it has sets for addition, subtraction, multiplication, and division and even tougher problems like fractions.  She was able to quickly figure out how to use it herself.  My one complaint is the screen is a bit difficult to read if you aren't in the right lighting.  But otherwise, I'm excited to have her use this as she goes further in school to practice tougher problems.  It's also a great size for the car or waiting for an appointment.  I received this product free from Educational Insights in exchange for an honest review.
