Buy an appliance only in a reputed shop, which guarantees after-sales-service
for a year or two. Go for brand names which you know last for years,
because your initial investment will be high.
Before
you go to a store to buy an appliance, collect literature about
the appliance from various shops or companies. Check out which model
has the features that you want and be prepared for the prices. If
you are unprepared, you could end up paying more for features or
accessories that you may never use. Buying well-known brand names
ensures quality of parts and the product as a whole, and also genuine
guarantees. Make sure that the warranty covers the whole product,
including the parts which may be hard to obtain later on or are
the most expensive.
