i definitely have to give a negative review for these like the others
it is so bad of a training ball, it really feels like a ball of jello. it is soooo soft, you can just push it litely and it will cave in, just think what happens when you are looping very hard. you can hear there is something wrong when it hits the table, it is a very high clinking sound instead of the normal full on smack sound. when you loop, it doesnt hold to you paddle. they are unnaturally soft, and NEVER should be used. do not let the low price fool you, get some better quaqlity trianing balls than these terrible!
