While I can't directly compare these builds to Lego as I don't own a similar Lego set, I can share my experience. I do have some Lego bricks, and these compare quite well. They are similar in most aspects, yet there are differences. Building the set itself was really enjoyable. The instructions are in color, although the printing made some colors look a bit similar. I'm uncertain about how the different bags were organized. As I haven't built something like this with Lego, I can't make a direct comparison, but a review I read mentioned that Lego instructions are somewhat easier to follow.
That said, after completing the first one, I went ahead and purchased the other three sets. At nearly half the price of Lego, these sets are a fantastic deal. I strongly recommend them!
My kids are currently big fans of Lego, so I thought this set was a fantastic deal for a highly detailed building. However, I didn't realize that it's smaller compared to regular Lego sets. My daughter still loves it and plans to use it as a play area for her Lego Friends characters.
Putting it together was similar to regular Lego sets, and there were a few extra pieces in the package (which was nice for me).
Nice building - many details and a good building for playing. More on my german youtube Channel
