Our children, ages toddler through 7, are all having a blast with them. I don't think there are any choking hazards apart from the bingo chips.

As I mentioned before, magnetic toys have a hazard beyond choking. If one magnet is successfully swallowed, no problem, it'll come out again in the usual way. If more than one is swallowed (or one magnet and one or more ferrous materials), then it can result in an intestinal blockage. Or, even worse, the materials can become attracted to each other across intestinal walls, leading to a perforation or other significant complications. In either case, the only way to get them out is surgery.

So, with a typical toddler around, this is a significant risk. I wouldn't have worried about it with my own DD, because she was never had that habit of putting things in her mouth. You have to figure out how this risk matches your own family.
