This was my first mystery kit and I was pleasantly surprised that it wasn't too confusing to do. Just takes maybe a little longer to check if you have placed all the drills of the current color.
The surprise aspect of it was definitely fun and the picture came out as vibrant as I expected it to. The mixture of normal drills, ABs and the new Fairy Dusts is really nice and gives it some variety. It's a little hard to see in the pictures, but in real life you can see how there are these subtle differences.
