Oh my god, putting this marble run together was one of the most frustrating things I have ever had to do. Took me an hour to put it together and about 0.4 seconds for my kids to break it. It's very weak as you can see from my photo, I couldn't get my phone to take a picture before it broke. One row of blocks is not enough to hold the tracks, larger blocks are needed. Don't let me start with instructions. The instructions they have are fine BUT YOU NEED TO ADD ADDITIONAL INFORMATION. For example how many spaces between blocks. Also add pictures from different angles to make sure they are in the right place. elsewhere as it will simply fall apart. Some good points are that this is a brilliant idea. The colors are bright and exciting. Another bonus is that it can work with branded blocks.
