It is a compromise.
A flashlight is not an aeroplane that can kill many people when it fails and has strict regulations for quality control. So there is not a minimum level that quality control neccesarily must be at (well, it must not short batteries out of the box, so there is a minimum even for flashlights). The level of quality control is is determined by the customers in the form of value for money, and by the manufacturer who has to asses how much money and effort will be spent on fixing and refunds afterwards (and reputation damage) and determine the level of QC accordingly. If a product is really cheap, customers (ought to) accept a sloppy quality control, a percentage of items that does not work, or only after a fix. And I demand my Zeiss binoculars to work flawlessly and be completely waterproof.
The Q8 is in between, you pay a fair amount of money for it and for that money you may expect it to be well designed, meet the specs, and work out of the box. But for this money it does not have to be perfect and survive a lifetime of abuse. I think and hope that Thorfire realises that (The Miller tells them that too ) and takes care of sufficient quality control.
