How to decide that is it original or duplicate product?

Yah, sometimes duplicate are good too. just for saving some money.

it depends on the accessories that u are going to buy from them.. hopely proccessors cant come duplicate... u can check them through my computer properties.. and motherboards also have their own driver setups..so people will not be so greedy to do such hard works for some bucks.. and about ram....u can get it from anywhere..its not that much costly... so dont worry..its all mith that comes to our mind before buying some new things in life.. [b]Keep lotting....keep earning.... byee..[/b]

as regard different hardware you can add to your computer it depends..such as some should be ok some really not!! So normally duplicate will be cheaper bcause the quality of his harware is less good than the original one!!So in many cases it should be good buy a quality product even iìf it will ocst you much because it would have a long life too normally the low quality hardware after sometimes can have many problems and so cause them to your computer too..so if you must buy critical hardware as motherboard,ram,graphics card and so on it is better to see a good and quality component for your pc..may be some storage or portable hard disk it should be also of different brands and may some cheaper so it depends..

Hi, net_ankit. Your concern is right, there are so many duplicates in market. Although there is no hard and fast rule to differetiate duplicates but there are some general steps that guarantee at least 90% safety. -Try to buy branded products from established retailers or dealers. The best way is to order the product directly to the company. - Branded products have unique IDs that can be easily tested from the company`s websites. -Try to purchase complete branded product, assembled systems have chances of duplication. Duplicate items generally have lower costs and their finish is also not that good as the branded ones. Use your question power to get the truth out of the retailer`s mouth.
