Ths product is very good, and basic requirements are filled. i just wished it had a key lock feature just like in D4500mk2. this supports my 1TB HDD, yay! BUT BUT ... be aware, once you connect it to a pc, you will face issues, just like i am doing now. I have contacted Numark, all i get is an auto response. The player is now only good working on left fader [PC] mode when connected via cable. I tried to reset by unpluggin during ppower on, but nop. Awaiting for Numark's response.
as per my research, the main board will need replacing,but i cant gaurantee that is the solution, as this is a software glitch/issue which can still re-occur. Guys do not do any software updates for this issue by yourself, you will spoil it further.
Edit: Rating increased to 4stars, as i appriciate the after sales provided by Amazon and Bajaao .. Shipping the product under manufacturer warranty.
