Always pays to have a few test set-ups so you can check things the moment you receive them. I always check motors, ESCs etc, as the sooner you find a problem, the sooner you can start the replacement process. Ali Express can make you wait for up to 90 days before making a claim, (this was recently increased from around 60 days) but they and Banggood are quite good with making their suppliers refund for damaged or non delivered items.
Not sure if things will change, as the CCP has put thousands of its own people in as workers after Jack Ma retired from Ali Express, (also infiltrated many other technology companies to 'keep an eye on business procedures' (yeah right!)
HK is part owned by an Aussie and has been slapped with a $2.8m fine required to be paid this year, so who knows what will happen to them (not to mention the Chinese takeover of Hong Kong with associated business interference). Their stock has decreased by about 50% in the last few years so the choices have reduced dramatically from say 5 yrs ago, (probably saving up for the fine😀).
