do you knowing buy less known brand because it is cheap

depends on your financial status,sometimes the cheaper things will do the same work as the expensive ones,you just choose what suits you best to buy,don't be too care of the brand or the cost,if you have much money you could just buy what you want without any thinking

You just have to shop carefully, and examine whatever you're buying before you buy it. Sometimes if you're on a tight budget you have to go with the cheaper option even if you are going to have to replace it sooner.

Most of the cheaper ones(not all) will also be good.Why did they become cheaper?Just coz' of no advertisement cost.These branded companies(but not all again) spend a lot on ads which are indirectly put to the customers.Regarding the spare parts of cars I think some parts of cheaper rates(not quality) are damn good than the branded ones.They might even last long than the branded ones.BUT YOU NEVER KNOW..lolz

I always buy a product from a good company. For example, even for buying "chips"

(eatables), i buy it from a good company, even the though the quantity may be small

the quality might be good. Buying goods from a local brand may cost you more later when

we encounter with repairs.

Cheaper does not always equal lesser quality; it depends. Sometimes we pay top dollar for the name of the product and that is usually a waste.
When looking at a cheaper brand it is helpful to examine the item carefully and assess the level of quality and whether it may cost more in the long run.
I find that with a lot of things buying second hand can save a lot of money without reducing quality providing the item is in good condition. I have designer label cocktail dresses that I paid under $20 for in an op shop which usually retail new for hundreds of dollars.

sometimes it works,sometimes it doesn't.
but parts is definetly something i wouldn't scrimp on.
food,maybe.the most you can get on that is a nasty taste.

wekk i would always want to try cheaper things but i always ask or inquire about the products by someone who has used them to know if they are good and if i get good reviews then i surely try.

I guess it depends, just because the brand is less known, doesn't mean the quality is less better. though it is the more likely the it is, that is why more known brands take advantage of the security that the consumers feel buying their product by raising their price a lot higher. I think there is also a difference between a less known brand and an imitation of a known brand. There is a certain drive for companies new to the market to prove the quality of their product to be as good as the known one.

I always buy the best that i can afford in replacement parts, this gives our machines extra life and so we make back the expense in the long run.

It depends on the item I'm buying. If is important, like car parts, or something I need to rely on, I will spend more and in the long run, I get more use out of the item. On the other hand if its something I really don't depend on, I'll go for the cheapest.
