What he said..
aares, unless you get really lucky, youre not likley to find anyone willing to give you, or even sell you cheap, a defective c3
The only way fr a c3 to be defective if for the bulb to be blown, or for the tail cap to be malfunctioning, clicky OR twistie, and in both cases, surefire indicates free replacement, or repair.
