Hi guys I've searched the forum and found nothing about these balls and how they play. I decided to risk it on **** and just buy the lot, seemed to good to be true of a deal. But after contacting seller he reassured me these are legit etc etc. Here are the pictures I decided to open one and can and see what the quality is like, it appears as though these are legit and all are pressurised. Regarding material it does not look great to be honest, I think it's because I got a good deal and once this happened to me before it turned out they were supermarket ****e balls. Just tested it outside in the garden and they do bounce but not as bouncy as the other branded balls but are certainly better than the no name brands. Sort of reminds me of Dunlop Championship tennis balls, seem to be hard and not as bouncy. Will test it on court and will give more feedback unless anyone else here as some experience with them would be appreciated?
