I owned one  for 2 days and i had a problem with the keyboard 10 keys didn't work as they should they had a big delay on the note of command,the feeling of the keyboard was great but ussles because it didn't work all 88 keys, and the other buttons faders and knobs are very low quallity are made from very low quallity plastic it feels like an 2 years old child toy.

UTILIZATION

Like I said i owned one only for 2 days and i didn't used it alot because I send it back to quarantie and it never came back.

OVERALL OPINION

My opinion is don't buy from ESI (EGO SYSTEMS INC) because you don't get any help and support from the company an all the products are very low quallity. I tested an Esi Keycontrol49+ and is the same ceap feel.
