I bought a couple Prime blanks from SoCal skate shop over the winter. Put them up on my closet shelf for a couple weeks, no closet doors and the air in here isn't too dry or moist. They were also stacked on top of other boards that were BBS/Generator. I took the blanks down one day and stood on them, was gonna maybe grip one up. Both started making crazy cracking and popping noises and then I look to see all the plies were brittle and cracked all over the place. The boards did not arrive that way, either. Stood on all the BBS boards and they were perfectly fine. Made me sketched out about any Prime board and I will never buy one again or recommend.
