Hi .everyone yes i went to croma and i was completly astonished razor products sold for like 50 % flat rate . Razor krait for 900 , cooperheard for 2 k and diamondback for 1450 . All were sealed box pack .. so i went ahead and bought Diamondpack for 1450 ..only problem is it doesnt have warranty as these parts were like 6-7 months old which were not sold yet by them.. but still i find its a good deal . the mouse is working good .. will post the pictures soon !!! i think its worth buing it !! there shouldnt be any problem.:hap2:
