Nope. My son has two Ozone 7s, two kids I teach, between the two of them, they have 3 Ozone 7s, my wife has an Ozone 4, and another kid I taught this summer had (broke the frame) an EXO 3 Blue. I've strung them all multiple times using the S-hook, including other customers with different Prince frames with ports. No damage...not even close.
Personally, I'm not a fan of Prince racquets, particularly the ported ones, but hey, to each his/her own.
