thats the point though isn’t it? At this level/price it should be consistent at least on the basics with no excuses.
you would nt accept an ‘oh well, it’s inconsistent’ if you had this risk when buying a car - as Jaguar found out in the 70s/early 80s. 30-40 years on
look how many Mercedes there are now vs Jags. In the long run inconsistent poor product gets found out.
