They are smaller than advertised 1/2" size. This is an issue for us as we bought them to use with the MarbleWorks race which really uses 1/2" diameter balls. The difference in size causes some problems. Smaller marbles can bunch up and get stuck in a race when launching multiple at once - this has never been a problem with MarbleWorks marbles. If your race involves a jump, the small marbles will fly differently and may not necessarily achieve the same thing. I was trying to save a few bucks but now wish me, I would have bought the MarbleWorks brand.
