So aren't they saying the casing is just temporary, it is supposed burn out, and the fire brick is there to do the real work?

[GolfGeezer]

Polarbear777 I can't believe it is intentional. The basic economics of the cost of making products, particularly at the price point of the MB products, would be to minimize any material costs. So, putting a grate in there that they "expect" to burn out is tough to comprehend.

[texastweeter]

So this is confirmed from MB now

[Razor]

Doesn’t make sense. Why is it there in the first place then? As GolfGeezer said it adds to the cost for no reason. That’s going to cost a beancounter his/her job.

[DavidNorcross]

Interesting read to say the least. Thank you for sharing.

[RonB]

Great job. I can read photos better than graphs...

[Henrik]

That firebox burnout looks downright nasty. And seeing it after one week? Hmmm.

[fzxdoc]

Yikes. That firebox.

[klflowers]

Wow.

[grantgallagher]

Damn!

[STEbbq]

Wonder what would happen if you submitted a warranty claim there.

[Polarbear777]

I'll let you know if they ever respond.

There's plenty of room for ash in this cooker, so the type of charcoal isn't important. Main longevity thing is the packing factor, or how much you can cram in the hopper and still close the lid.

Since the limit is about 12 hours, seems like they could have made the hopper taller, or just add on an additional section as an option and you could get it to run 16 hours untouched. I'm guessing the 12 hours will be more like 8 with a heavy load of food in there, will have to try that assuming I can convince myself that it is still safe to operate.


I'm sure the firebox isn't lined with thick stainless because that much stainless would increase the price by ~$100, and since air-blown charcoal can exceed 1500F, it may still fail.

[Troutman]

Thanks for the thorough temp analysis and review of this cooker. Shame they had to compromise on the very thing that may fail the quickest.

One thing I always check when buying a cooker is avoidance of tin can metal components, a proper grease handling system and simplicity of use (less moving parts the better). Not sure this cooker, although unique in design, doesn’t seem to hit the right notes for my criteria.

[Polarbear777]

Grease routing seems pretty good, though I haven't tried to push it yet.

Great write up Polarbear777

[Jpe616]

Hmmm.... I was seriously thinking about grabbing one of those since the smaller one was pretty highly rated on here, but I wanted more cooking space. After seeing that firebox after just one week, seriously reconsidering that.

[BFlynn]

Not sure I'd even call that a firebox. More like a foil liner.
