Once I tried the woodflame I was sold.
It's a battery operated BBQ that burns wood to cook your food by blowing hot air from the bottom up. You can have all kinds of smoked taste as you can burn many different type of woods like cedar or pine...
Seriously check it out, I have been making the best tasting meals on this bad boy
