Agreed with most of what has come before, and a few observations from owning and using one over the last year or so.
It’s not portable, thats it – we’ve got a small one, and even with that its not portable.
Its taken a few goes of stuff to learn how to use it and get it right – it does way more than cook burgers. If thats what you want it for, get something else. Done a few “long and slow” joints, and it’s be bloody amazing
It won’t hold a high heat for ages to give you a proper chargrill as the whole thing gets so hot – ie it works like a kiln.
Size wise, get one that will do a whole cook including corn / veg if thats what you like
As with all charcoal BBQs it takes a while to light and heat up – some careful planning needed as to when you eat etc.
Enjoy, food taste and texture is amazing
