SO true Aussie.
The other thing I would mention is that Manufacturers, after introducing quality control, should GUARANTEE their products. In other words, if any products are defective they should be happy to replace the defective products.
If that was to happen, Buyers would JUMP to purchase such guaranteed goods.
However, a SMART Manufacturer would know that he would very rarely have to replace goods, IF he has a GOOD quality control system in place.
