Thankyou, I actually found a review of these on youtube last week and ordered on next day delivery. I have done 5chapters of the kanji one already it's really good!
If any other UK buyers come across this I got them here http://shop.jpbooks.co.uk/product.php?id_product=80252
I also have the older addition of this and it has even more questions to test you http://www.amazon.com/Japanese-Kanji-Power-Mastering-Characters/dp/4805308591
