A few years back i used to build PCs, i had to use BTC parts in order to keep the prices down. This is my experience with them:
CD drives will not do audio extraction properly.
Monitors failed after a year.
Keyboards.......well, those can take a beat
Mouse, the movement goes crappy (you know the pointer starts to dance) after 3 months.
Speakers.........lol, need i say more?
I had only bad experiences with those brands, a lot of parts going to warranty in such a short period of time.
Liteons.......on the other hand, are just as cheap as BTC burners, and much better.
If you were in a world full of crazy people, who would be the crazy person? OTCentral
