Just used my new AMNST in my MPS 2 door. Worked great. I removed my water pan and chip tray. I used a rack on the lowest setting for the tube and offset the tube to one side. It lit as promised and burned for a solid 3 1/2 hrs. It would have went 4 but I forgot and had the top vent wide open too long instead of adjusting it. I smoked a really nice almost 2lb salmon fillet that came out great. I know because I'm cheating and picking on it. Man it was nice not to keep popping out every 30 or 40 mins to reload chips. Great product that I would have never known about had it not been for this forum.
