I am in my second control booklets of this collection. The 1st time I was surprised by the format (small booklet of about 6cm on 12cm), I expected more but finally I am very satisfied! It's very convenient, there is full of news, information, databases rules! My children (6 and CE1) and I consulted regularly with !! I recommend to have in his "library" !! Especially considering the price .... you can afford to buy all of them !!! ;)
About delivery, as usual, satisfied !! Fast shipping, well protected !! Never had a problem on that side with amazon !!
