Fridges come to mind, but it depends on what you mean by “quality”. I had a 8 year old fridge, and attempted to replace a shelf bracket that broke because the plastic was flimsy - no parts available after 5 years. By 9 years old the brackets that held the large fan in the back of it in place had crumbled to dust.

Meanwhile fridges from the 1960s are still humming along fine.

The crumbly new fridge is more energy efficient by a long shot than that workhorse hold fridge - so it does depend on what you consider quality, but longevity and repairability are definitely major factors in what I consider quality.
