It is important to take both into account before you 'will' (niepotr) decide to buy some kind of these products.
One major advantage is that the brand name products are made 'of'FROM better materials. If you buy 'this products' (this-odnosi sie do l. poj, a products-to l. mn, albo jedno albo drugie, tutaj odnosisz sie do l. poj to popraw) you believe that the quality is good and it is reliable. If you buy something of well-known brand, you know what you can expect 'about' FROM it.
You can feel that THE things you possess are fashionable and stylish. 'By' (moze lepiej 'with) these products you can attract attention and hear some compliments.
This kind of products 'also can' (zla kol slow) 'approach' (zle slowo, napisz 'bring you closer') 'you' (niepotr) to your idol or TO some famous people who very often wear brand clothes or have brand products.
On the other hand, brand name products 'have also' (zla kol slow) some disadvantages. The main downside can be that brand name products usually have higher prices than THE 'generics' GENERIC alternative. This situation can cause some 'troubles' (lepiej TROUBLE) 'with' IN 'connetion' (ortog) to other people. Sometimes people who have not GOT brand name products are not acceptable in society.
A lot of people, especially in (brak przedimka) city, can have the same gadgets or clothes because shops which have these products 'in the stores' (niepotr,'shop' a 'store' to jest to samo-jedno w BrE, drugie w AmE) are very common. But if you buy generics you can be sure that you have (brak przedimka) original style.
I prefer buying 'generics' (lepiej generic products) because these products have lower prices and often the same quality of material like brand name products.
