Mukhang ok naman yan... depende lang talaga sa manufacturer dahil iba iabang manufacturer gumagawa nyan, yung original, na-clone, tapos yung clone na-clone pa uli. Yung design kasi nyan even the pcb and casing parang naging standard template na. Its all the same, they use the same IC but it will differ with the quality of the casing and other internal components.
Yung cdr-king version ko, nasa loob lang ng kotse exposed to daily extreme heat inside a parked car in the sun everyday. Working pa siya everytime I check once a week.
