It's been a while since I use them and my time is not so bad of the matter. I have no particular criticism to make on this little jewel: the loops are of a quality harsh environment, the handling and super fast sratch (although I very rarely used) in good quality.
I use them in the evening and use it with other DJ's attention when some hardware is not theirs ... They are always so solid Impeks foolproof, pioneer you might say !
The report seems qualitprix exellent. I test the CDJ 1000 and I find it does not justify its price, there are plenty of function but did we really need a good box was indeed a sampler and you're jou ... In addition they read the CDR-W, which is not the case for 1000.

DENON turntables seem quite as she read the most personal MP3 but I have not had privilge to test them.

I put 9 / 10 for the MP3 but otherwise great product to buy eyes closed.
