I use one for jerky and pork butts. I do not like brisket on one....I can make a decent brisket on a offset smoker. When i tried one on the electric it just tastes meh at best. Pork butts taste fine though.
The little chip tray is too small unless you want to nurse it all day and if I had to do that, I would rather use a real smoker.
Instead of the little wood chip tray, I use a stand alone pellet tray (made by Amazen) placed inside of the MES.
The place this thing shines is when I want to make a pork butt....
season butt
set temp
load pellet smoker thing and get it going
put on meat with good probe
go to bed
pull meat when it gets to desired temp
let it rest until I want to eat it.
It is an easy button for pulled pork. Put on meat the night before and with the pellet tray, I can just check it a couple of times if I am having a hard time keeping the pellets going vs tending a fire all night.
