We have just started using it and I think it is excellent but my 9 yr old daughter is still doubtful. She is phobic about Maths and I have found it useful as a diversion from my relationship with her, so we have less conflict, and she can use it in my absence as well. We both like the Australian male voice. We have called him "Jonathan". The lessons are short enough to keep her attention for the time required to teach her something, and the tests are good because she is beginning to see signs of progress which is VITAL to raise her confidence and improve her attitude to Maths. She lacks confidence because her fellow students mock her at school because she is supposedly 'bad' at Maths. On the downside, she said the lessons were 'boring'. She is a very visual, kinaesthetic learner so she would be more entertained by the use of humour, personified numbers, pictures and suchlike, but you can't have everything!
