Is Studiemeester for my child?

I contacted Studiemeester to find out if this product is right for my child. I asked them to send me more information. I requested them to send me a exam paper for Grade 4, NW for term 1, my child already wrote this exam. I just wanted to make sure that the content was really going to help him. They did tell me that they specialize in summaries. They wasn't very helpful and did not want to send it to me. I've got a problem with paying money for a year, just to find out that this is not helpful for MY child. There is also not a lot of examples on their website. They wasn't very friendly and I will not buy their product, just because I wasn't convinced this was the right product for my child.
