Fair warning. - Streamlight ProTac Remote Switch W/Tailcap

Seems to be of equal quality as the one that came with my Streamlight Protac Rail Mount HL-X. Can't exactly say though because the end that's supposed to go onto my light is instead meant to go INTO a light.
Don't know exactly which model light it's meant to pair with but mine isn't it. I would return it, but I opened the package before checking so I suppose I'm stuck with it...
