Package arrived in good condition though external box conner slightly dented, item inside is intact with no damage. All items received as discribed. However when tested unit , the connection of the drives always disconnect on and off. After numerous trial ,finally discover the usb connector cable is faulty . After discard the original usb connector cable and connect with a new one, everything work fine. Supplier should have xheck quality of cable supply , I could have mistaken the unit itself is faulty, wasted quite a lot of my time.
thanks
