KiwiCo crates?

Anyone has any experience with kiwico crates?

They seem interesting to me but we're in Europe so English is only our 3rd language and shipping is expensive so I want to know a bit more about user experience.

We have a 1 month old, for whom I'm specifically looking at it.

We also have an 8, 11 and 14 year old..

For the 1 month old I'm wondering if we can use most of the box, since he doesn't read yet, but I saw there's a book to read from. The 8 and 11 yo can't follow the english instructions yet but seem to have the most fun boxes.
