I do apologise for ever doubting that you are a total pain in the hole.
I will state that I too will not be screwed over and have had particular success on more than one occasion in getting satisfaction out of DJI having bought their faulty gear. Not via the reseller, who is generally powerless and has as much trouble with DJI as we all do, but directly with DJI in China. Not 100% of the time but certainly for the expensive purchases. It took considerable persistence but they did bend in the end and replaced the items at no further expense to myself - or the dealer.
I am totally with you on the whole UK law etc. etc. but you should know that DJI treats their dealers every bit as badly as they do their customers. The dealers are obliged to buy excessively large amounts of stock and then, when they have amassed this huge stock, DJI introduces Mega deals and special offers. Now all the customers expect to pay the new low price and the dealer is left with large stocks that he bought at the previous price and can only lose money on because DJI do not reimburse the difference. DJI dealers have to replace faulty gear from the their own pocket most of the time because DJI will not send them replacement stock. The dealer also has to pay from his own pocket to ship the faulty gear back to China.
So you can get as hoity-toity as you like but they are chinese, they are ten thousand miles away and they don't give a fig about the rest of the world. Why do you think they are such a despised race?
Good Luck Raymond
