Geoff, a financial advisor and keep-fit ennthusiast, bought an exercise machine from Ben's sports goods shop in Arusha. The sales note contained the clause that it is for the buyer to ensure that the equipment is suitable for his personal needs.

Geoff used the machine regularly for four weeks. He then noticed that he was experiencing back paid and telepohoned Ben about this. Ben said that there was nothing to worry about.

Geoff continued to use the machine for another month, but then suffered serious back injury when the saddle on the machine collapsed while he was exercising. It has now been established that the dimensions of the machine were unsuitable for a person of Geoff's height and build.

Advise Geoff. Would your advice differ if Geoff was a professional athlete and had bought the machine for the purposes of his athletic training?
