Re: How they test matters
This sounds a lot like Apple and their extremely comprehensive handling tests done on the iPhone X, which because it was so super-secret all had to be done indoors in controlled conditions. Conditions which included making sure the hands of the test users were always dry, not-slippery and not likely to fail to get a grip on an all-glass extremely slippery and extremely impact-sensitive expensive shiny thing.
Which stole the crown of most expensive thing commonly dropped and broken from the likes of Samsung and Faberge et al.
