A blender is one of those nifty kitchen appliances that can cost you either a fortune or just peanuts. And you would certainly not like to spend the former in buying one.
The first thing to remember is price is not the most important factor for a decision. Certain expensive models can turn out to be disastrous while a lot of cheaper devices can be really reliable. So, you can start with a comparison of types. You should consider over the available options. There are high-performance blenders that can be useful for all kinds of drinks and soups. There are the more conventional devices can be good enough for just smoothies.
Then, there are even simpler models that are just good for more casual blending purposes. Finally, there are immersion devices than can do a neat job of chopping up veggies and fruits for soups and smoothies. You can decide what type would you like to buy. It all depends on what you need from your choice of a blender.
The next thing to consider is storage. Blender comparison should consider the amount of storage capacity that a device can offer. Again, this is subjective to whatever your needs are. If you are planning to make juices and smoothies every weekend this summer, you should look for a bigger and more advanced type of blender that can pack in a lot of fruits.
On the other hand, if you just need to slice and dice or make a bit of soup from time to time, a lesser advanced machine will do just fine. Remember that some blenders can also have multiple mixing containers. But it can be a bit of a stretch to use them all.
When comparing storage and types, also look out for unexpected features among similar models and categories. This will help you to make a better buying decision.
