Just curious on shipping feedback from those of you that have ordered items direct from DJI. I am thinking of purchasing some parts directly from them. Likely will scoop up one of their P3P 4K /gimbal cameras also. I'm currently in Canada and see they are offering free shipping vis DHL. Any duty, brokerage fees, taxes, etc. to be ready for? Any feedback experience on shipping time, arrival date vs ordered date and extra fees?
