I bought a 256 sdram pc133 and a 64mb sdram from him. Pag install ko ng 256mb sa computer ko sa haus and office , pareho nag register ng 128mb lang. i tex him na defective na yata ang mem nya at gusto ko isoli kc 2nd day pa lang at 3 days warranty and bgay nya , pero he insisted na luma daw board ko, so i tried on my friend's computer na p3 din. 128mb pa rin. i tex him again and hindi na cya nag reply. don't trust this guy, be careful when u deal with him or don't deal with him at all.
