We are really happy with these pucks, but did not think to check the weight of them. We have a full size air hockey table and they sometimes stick in the return because they are too light weight. They are still fun to use since they are different than any we have seen and they look really cool when they spin. I would order them as an accessory set, not the main set - but still order them because they are really cool (my seven-year-old loves them). 5 stars
