I got a Teifoc kit as a kid and came back as an adult to try a more sophisticated set. It's hard to estimate the time it will take to assemble this set from the pictures, but with almost 500 bricks I've spent about 30 hours and I'm almost 90% complete. I'm an adult who loves to lay, but the patience required to get this set to match the pictures on the box is essential. A few things to note is that while the accuracy is very good for the same type of brick, the difference between the depth of the swept window and the depth of a traditional brick is 2mm. There seems to be a slight difference, but you will see from my photos that the swept window brick is not flush with the wall. There are multiple stone size options which makes it difficult to be accurate and it gets annoying when you've already laid 400 or so stones and it becomes difficult to maintain consistency. Of course, I am sure that these tolerances are still good for children.
