What is 'satisfactory' depends on the goods, the description about the goods – but particularly what a reasonable consumer would expect of those goods.
Goods must not only be of satisfactory quality, but they must remain that way for a reasonable period of time.
A reasonable test might be – if you buy a mobile phone for £200 and it stops working after two years. That means that it has cost you £100 a year. Would a reasonable consumer purchase a mobile phone which effectively cost £100 per year and then need replacing?
Another test might be – if Samsung or HTC or Sony advertised a mobile phone and said 'by this phone, it will only cost you £100 a year and then it will stop working' – would you or anyone else by one?
Section 9 of the Consumer Rights Act replaces section 14 of the Sale of Goods Act
