It's definitely true. I purchase the balls for my club and we are spending a fortune these past few years on new balls. They don't last any length. They go out of shape very quickly and do not retain the firmness of a new ball. As far as i know they are made in far east (of world, not ireland).
Looks like a deliberate thing to me to sell more balls.
