The connectors to the Testors mini-blue compressor are obviously meant to work with their Aztec line of airbrushes. They will work fine with other airbrushes, but you will need to use the universal connector that was supplied with the mini-blue, than purchase, probably at a home depot, any other connector you may need.
Mine works just fine,but I did hear of a lot of people complaining that it does not push out enough air for some airbrushes.
