This thing does not deserve comment.
Should prohibit the marketing of this type of scam!!
Today stored in a box in the cellar, these decks are étées the worst investment of my life. It n'on fonctionées that one month! (Fonctionées is a big word as the cue already had serious problems from the first day)
I highly recommend these decks even beginners. I am 6 months now the proud owner of a Numark CDN22 (thank you for your advice Nikow13) who has never had a glitch ... I do not have that choice would do with the experience.
