This is my second of these units, I sold my other to accommodate a move over a decade ago I am confident It would have been working still. I have late hours and a preference for quiet. It’s solid and like a heavy little suitcase so easy to handle and not going anywhere. I like sketching in airbrush for the distance factor, this machine keeps up. I also appreciate aspects I hadn’t really used on my previous run, such as having a compressor to fill pressure tanks in resin casting.
