I haven't brought any cases of ESP cards yet, the upcoming NRL release will be my first case for ESP. I did however buy a set of parallel ESP from last year and over half the cards were damaged. Hope it isn't like that with this upcoming series.
Last year when Select had their final NRL series of Dynasty, I purchased a case. Over 2000 commons were damaged and all of the higher end inserts including signatures were all damaged. Select did replace them for me though card for card, which I thought was outstanding.
