Retailer reviews
Summarized retailer review data when available.
If you pay 116 euros, you should expect a decent set and a number of building blocks. Overall, a very small box with 51 pieces. What justifies the price compared to what you get? No. This will be returned.
Well thought out, but space doesn't really appeal to me, and then it's quite expensive for such a small thing. If you're really interested in it, then it might be worth buying, even if it's just because it's one of the first sets in the line.
This box was quite simple, with few pieces. This was a bit disappointing compared to the price.
