A toaster is one of the most durable catering equipment in your kitchen. Expect that if you have a good quality toaster, you will use it for years. But since today, there are modern developments in the toaster, I think you should consider throwing your old toaster away and buy a new one because of the following reasons:
Older toasters consume more energy than newer version of toasters. The energy star rating is the most useful rating for appliances and catering equipment to date. Before, toasters and other appliances are not rated this way so we end up consuming more energy than what the toaster usually needs.
Newer toasters are safer. The development of new technologies are applied to newer toasters therefore you will see features like auto shutoff, pre-heat, and some even have computers inside to calculate and determine the toasting time of bread.
These two reasons are enough to convince you need a new toaster.
