I received my dgx 670 Yamaha keyboard and the product itself is fine but it arrived unheralded from interstate and was left on the doorstep against the front door partly exposed to the rain on the Thursday afternoon of a long weekend with no phone contact to let me know the courier was dumping it there ( even though my phone number was easy to read on the box) I arrived home at 7.30 pm and had to try to lift the 40kg huge box in the front door ( after trying to access the door) On checking the tracker app at that time, it still said the keyboard was in south Australia (not NSW) So, in short, the courier service and level of communication was appalling and I am lucky the Keyboard was still there - had I gone away for the long weekend it would have been a different story
