I think the weakest link in this racket is the grommets. In the past, I've owned a GP-9, GP-5, Mystic Power 500, TC500 and Luminasonic 5. I notice that the grommets gets worn rather quick. My TC500 grommet is worn so bad that you can see the frame. I know shuttle-house sells the replacement grommets for a few bucks, but I'm not to worried about as I don't really use it anymore and it's just sitting there collecting dust.
