With a ton of different blender models available, it can be a challenge to determine which is right for your needs and budget. Many leading companies make blenders. Many people believe it's a good strategy to buy a quality blender from a brand that you have grown to trust over the years.
Cheap blenders can work for one year or more or need expensive replacement parts. The main ways that blenders differ are their power, what they are made of, and the features they have. A stronger portable blender will always be more useful because the less powerful blender may have difficulty destroying ice for smoothies and ice cocktails.
Metal blenders may look better but may need a little more cleaning than plastic models. Blender jars usually come in glasses and plastic. Glass jar is usually more attractive and easier to clean, but it can be quite easily broken if it falls. Plastic jars tend to be harder and will not be easy to crack or break. If you anticipate using your blender for difficult tasks every day, you might want to consider the industrial or commercial model instead.
It may also be helpful to read reviews online and ask your friends which blenders they have and whether they like them. Buying a blender is a very personal choice and if you spend the time to understand your options and needs, you should be able to buy a blender that makes you happy for the long-term.
