I started my BBQ journey on the smaller cook chamber version of this.
It's cheaply made, has flexible legs so you have to be careful dragging it around or one of the legs may fold and it's very thin so it does not retain heat at all.
That said, I cooked some of the best pork ribs and small brisket I ever made, period, on it.
Beginners luck probably but it cooked what it cooked.
I started fires with briquettes and switched to very dry oak for the cooks.
It needed a heat shield above the area where the firebox mated with the cook body to keep the heat/smoke from clinging to that side of the chamber so I often placed a water tray above the opening.
Get the larger Heavy Duty vertical offset. The smaller box style offset needs mods just to function acceptably. The larger model just runs better. Don't waste your money modding an inherently flawed cooker. If price is the limitation, buy a used OKJ Bandera or something.
