Comments about Product: Really fun, high quality toy! Keeping my three year old engaged for about an hour a day. A few design flaws though: Pieces don't interlock tightly making some maze designs wobbly. So with a high energy three year old, one false move and the maze can get knocked over in in a flash. Also the manuf. choose two similar shades of green for the blocks. When looking at design instructions it is hard to tell which green to use....not a big deal, just slightly irritating.
