Ibiza Sound IDJ-2

Bought in December 2013 to replace my drive Minidiscs I used to live broadcast playbacks dance music equipment, I prom with a midi accordion. DJ effects do not really interest me, I look especially large storage capacity MP3 tracks on SD card or USB, but also quick access to the securities to be listed in order, either alphabetical or numerical to follow a directory. SOUND ENERGY seller assured me that this was what I needed for this. Nothing, ranking securities on an SD card is a real test, asking an amazing time and manipulations over end, result: the titles lose ranking expected, screen displays escape without stopping, select a file or folder is an achievement microsecond! . The manual of the device gives no advice, the technician of the store does not know and says grand'chose DJs who use this device (even with 500 recorded titles) carefully copy down the computer the same "title" followed a number in parentheses, followed by the title itself rewritten letter by letter! I tried everything to enter and classify 10 test pieces in a single folder, the machine does what he wants! The price / quality ratio is very bad, 198 euros for something useless, impossible to sell. I'll ask you repay me, but it is not won ...
