I just got this in the mail today (in case you're wondering, I got number 10,746). We all know how good the movies are, and if you're looking to buy this, you obviously like them a fair amount, so I won't bore anyone with a review of the movies. Despite there being 13 reviews here already about the movies or comparisons to what the US gets, I thought it was worth reviewing the actual boxset.
The box itself is very nice. It's hard and sturdy, certainly not a cheap job. You'd have to put quite some effort in to break it. You open it up and you get two fold-outs of discs and a nice little photo book. The book is quite nice. It's full colour, hardback and very nicely presented inside. Certainly nice for collectors. The first fold-out is labelled 'Years 1-5' and has a Blu-Ray disc and DVD disc for Philosopher's Stone, Chamber of Secrets, Prisoner of Azkaban, Goblet of Fire and Order of the Phoenix. The second fold-out is labelled 'Years 6-7 part 1 and 2' and contains a Blu-Ray disc of each of the three movies, a DVD disc of each of the three movies, and a Blu-Ray disc for each of their Special Features.
However, despite my 5-star rating, it's not perfect. As you're probably thinking, there's no Special Feature discs for the first five movies, only the last three. The only other bad point is there's no kind of latch to keep the box closed. The lid just flops open when you place the box on it's side on your shelf. Prop it up against other DVDs/Blu-Rays/Books and you should be okay, but a bit annoying nonetheless.
Outside of those two bad points, it's a solid box worth every penny.
