I use them in the evening for 4 years with mixer Numark DXM 06.
They are very functional turntable, easy to use.
Balance after 4 years of service:
Pros:

-Usability
Fast-loading CD
LED lighting-tray
Bon-track followed in spite of strong vibrations and sometimes very damaged cd - The CUE Play (it's one of the few models on offer)
-Very good effects
The loop-functions (stutter or component), two loops can be stored
Pitch-and KEY
-Ability to store cue points 3000
-Value / Price
-Ability to synchronize the decks

Cons:

The ITS-: lack of output gain (compared to other turntables dj) and
Particularly audible breath
-Loading CD drawer (rather archaic and cumbersome)
-A manual too small (many tricks are not on the detailed manual for mitigating the various bugs)
-The lack of digital output (not very useful though)
No-read CD-RW and MP3 CDs
Denial-of CD than 80 minutes!
-The size compared to the Denon or Pioneer CDJ-400

NOTE: Given the current price of AXIS9 must not ask too much either ...

Problems encountered:

Overheating of the CPU on a plate. Symptom: The display Bugue, messing reading followed by a smell of scorched
In short, the deck was unusable, (the balls when you have to start the evening in 2 minutes!)
She started to walk after two days and since RAS, go figure ...

Disappearance of the touch-sensitive plate on both decks so more features scratch and effects

Conclusion:
The axis 9 is a plate at the right price / quality ratio is easy to take control (even for a novice).
I do not regret my choice at all.
Currently, if I have to make a choice, will have a board with more input
USB as the Pioneer CDJ 400.
