Well i've had my for two months now and have used it in both lounges and clubs and i can tell you this from my experience, the vms4 works great!! The sound its clear (dont hear any of the sound complaints said about said controller) and have not encountered any other problems(hope this doesn't start one ,lol) The only thing that sucks is the help or lack of in this forum. I would have returned it a long time ago because i hate how this forum for which it's suppose to be made for dosen't help many people that ask for it. I know fleshfluke and others try but i feel more people in the know should be here helping the ones that don't know anything or need help mapping this great controller. I really hope this changes and the new mappings come soon ( i purchased this because on the website it stated it would get those mappings soon). all in all i wrote this to express my love for the VMS4 and the dislike of the help here.
