At first I was hesitant about ordering the ProV1X's from Great Offer Stock, especially used ProV1X for many of the same reasons anyone else would have their hesitations. But when I received the set in the mail, I was pleasantly suprised by not only the quality of the golf balls but how many were actually in good condition.As soon as the order arrived I cracked open the boxes and took out every ball to inspect their quality and type. I had initially assumed that there would be ProV1X's from many generations, maybe including some of the new X's, which are not nearly as good as the years past. Every ball was a ProV1X 332, which is a solid ball and was happy to see consistancy.As for quality, I did not expect to get 50 top notch golf balls, because lets face it, that would be shocking. There were 6 balls that I deemed practice balls, suitable only for a chipping green, and 2 that I will put into a shag bag to be hit into some hazard or someplace where balls go to die.Out of the 48 balls, 40 were in good condition with 4 looking new. Since I am fairly particular about the ball I play (only ProV1X's and Callaway Tour i's) I was happy to see that I have 40 playable balls.I know many good players might be detoured by this offer but I would encourage you to give them a try.I am a below scratch golfer if anyone needs reference.
