Bought a Masterbuilt Electric smoker a few months back and have been using it a couple times a week the past few weeks. I posted in the AMNPS Tester Forum about the sawdust probably igniting and instead of lasting a few hours, only lasted about an hour. I really didn't want to build a mailbox mod but ended up having to anyway. Right now I don't have it hooked up to the smoker, but I did put in about 1/2 tray of dust, sprayed inside of box with some PAM and let it season for a few hours. Will be doing a pork loin roast tomorrow, hopefully. With the short cook time on those, it will be interesting to see what the results will be on smoke flavor. I don't do a lot of cold smoking and just didn't want extra stuff around the deck.
