I believe vapors a (if memory serves me correctly) offers the proper hex key for a few bucks more with the orchid. It's right there in the options it has when you're adding the orchid to your car, right along side like silica, juice, batteries, etc (they try and get you to add on as many extras as they can while they see you're in a buying mood to get a device lol) hope that helps good luck. Is still really be interested in seeing a comprehensive head to head with a KFl + v2 by someone like Todd, pbsuardo, or rip trippers, but there really isn't much in the way of reviews for the device that I've been able to find.
