depends on how you view it...to me...its worth it...cos the strobe light comes with 1 year warranty....the controller can be placed anywhere inside the car....the module is waterproofed...you can adjust between two level of brightness.....and comes with 15 modes of blinkers....im trying to set a special ZTH bulk purchase...items will be arriving soon....price would be in the region of the RM400's....anyway...those who might have seen my car in USJ2 should notice this light...cos i bought myself the exact same strobers except mine came with alarm add on...when i lock my car the strober will blink...and when my car's alarm goes off the thing blinks madly...hokhkookhkoh....since my HID is low beam...ive been using this as a high beam for those stubborn roadhoggers...works like a charm....HAAHHAHAHAHAHA
