It's all about learning your tools. I tried BigDaddyJT's charcoal loading method this weekend (u-shaped charcoal instead of just filling the basket to the top) & used significantly less fuel... I've always been a stick burner, so I had to learn how to cook low & slow with charcoal while also transitioning from an offset smoker.
My Safe cooks at a very stable temp with no fuss. There isn't a single thing I would change about its design & I would recommend it to anyone (though I bought mine used for a lower price). My only complaint is that they don't answer emails.
