I have a small personal structure 3 sono running every weekend we specializes in wedding and karaoke + / -100 a year, I opted for this type of decks for the convenience and simple I 4 CDJ10 running since the beginning of its marketing + 5 years I have never any down 2 CDJ15 IDEM 3 years and 1 for 1 year CDJ15X IDEM all these people running every weekend is no problem for reliability . The only small problem they are sensitive to vibrations, the very effective trick I have in each flight case mounted on a double bottom of cylinbloc (the double bottom should not touch the edges) then the player is on the double bottom with the mouse anti-vibration 1.5 cm and more prob !!!!!! see pictures on our website in various http://avf25.kikouli.fr/ For burned CDs no problem, for cons for CD sales is more sensitive, for cons I do not agree with the member for indolove no prob transport compared to other brands, we also have a drawer turntables, a sound system for this kind of decks we have to throw them away every year because they do not support the vibrations of transport even in good marks! I am available for any explanations. @ +
