I do not think I can possible write enough good things. I have homeschooled 2 twin boys both special need if I had used this things would have been different. I bought this for my twin 3 year olds to help them. My 3 year olds fight over them and can sit and do up to 11 puzzles at one time. That is how good the product is.  The visual discrimination exercises are very impressive. It is one of the first products for visual discrimination that does not require fine motor skills as well.  I can see how this would help with reading skills later on. My package came with controller and 14 workbooks each with 11 puzzles. The work books start out simple from matching the same picture to matching same picture in a different color or different angle. then the puzzles advance from there.  I started using it for my 11 year old autistic son and he does one workbook a day so he will easily be finished with it in less than a month. I have seen huge improvements in his attention to detail and concentration in just 4 workbooks. I use it between writing assignments to give his hand a break from writing. When we finish the product we will be donating it to a school for autism. I feel this is a much needed program for typical to special needs. It was the best 94 dollars I have spent. My only complaint is I had a hard time figuring out how to use it and read the answer key. I watched the tutorial on you tube. I felt pretty stupid when I saw how easy it was set it up showed 3 of my kids and they have no problems.
