I searched for this unitl back in February tight after I got my Masterbuilt Electric smoker and it was sold out everywhere.  They emailed me saying it was in stock and I jumped on it! Since then I have cold smoked 30lbs of cheese, bacon and even salmon. This item is worth the price! One thing to watch is that chips might get stuck in the tower and not feed all the way down. Just tap it or use a wooden dowel to push it down. Very simple easy trick.
