I did a lot of research before purchasing this set. I wanted to use it to entertain my kids while flying. The only downside I can think of is that the squares aren't exactly square, but they're not much different. The magnetism is really light as others have reported, but we had no problem moving shapes during turbulence. They don't move for about 30 degrees, which is fine for my purposes. The parts are very well made, the size is small but workable and the bags that come with it are very useful too. The only thing I can't report. It's durable as we recently bought this set but it looks nice. I recommend it without hesitation.
