Some of you may have seen this in my Monroe swap pics. I bought this on a whim because I thought it was pretty cool.....my question is can anyone tell me about it, it appears to be a "gimmick" item where you show how a new plug works vs an old plug under compression (it has an air hook up?) I tried it out with no air and it fires the plug you have hooked up and you can see it in the reflective mirror, it has all of the adapters in place which I assume are for different plugs....anyway any info on this would be great ! Thanks, Steve Z
