Even the unpopable ones break! Sure they are good when new, but roll em around on the floor, scraping against stuff etc, they dont last forever. And who checks to make sure they are still good? Nearly nobody, they wait till one day the ball is flat, then try to pump it up, “oh a hole”
Stupid balls, Keep em in physio dept’s and out of gyms/health clubs/ PT studio’s.
oh yeah, i got a Letter just the other day, wanting to know if i want to run OUTDOOR bootcamps using these very Balls! OMG…
