if you are to ask if they are secure, they are. just look for the versign logo. but somehow, the cost will be still almost the same. better get the one from the local dealer, at least pag sira, pwede mong papalitan.

you may use onlines stores if you have no option to get parts or accessories locally. ako, i got a serial RS-232 cable for my old Casio QV-10A digicam from New Zealand pa.
