I have two MB electrics. Had them way before I found this forum. The first was a bluetooth version which was fraught with issues. It's still sitting on the patio next to the other one which is still functional. I never figured out what wrong with the first. Claimed warranty with the first and HD sent me a check for enough to buy the second. The second had some control issues and it was before I found this wealth of knowledge. I found out through googling that the MB controllers had heat issues. (imagine that) removed the controller and added spacers between the controller and the top of the cabinet. I has worked fine since then.
I'll probably get jinxed for saying this but I still use it for "short jobs" where I don't want to waste charcoal in my
WSM for a 1 hour cook. I mostly use it for pork bellies when making bacon or a tri-tip with low heat..\
If you don't want to go all in and make a "mailbox" attachment I would consider buying a "smoke tube".
If my current MB electric takes a poop, I'll probably buy another.
