Hola, so if you choose to purchase the good decks SYNQ XTRM-1, know that the books with felts are not worth a nail, a piece of cardboard round with what might be called the " smooth ", but that's not enough, our beloved discs do not deserve this! The plates are very good (cest not subject) but buy a pair of felt at the same time.
I do not put zero-because they are the same!
