I have a Go Anywhere Gas and the (v expensive) adapter. You can’t roast a whole chicken on it, and you can’t easily do indirect heat as you could with the charcoal version.
We bought it for camping but use it almost exclusively at home - it’s brilliant for steak, chicken and chargrilled veg etc and it only takes a few minutes to get it ready to cook - great for midweek barbie supper.
It has the usual Weber finish, so it survives happily outdoors all year round. It comes apart easily and you can chuck most of it into the dishwasher. Packs small when clean. Excellent bit of kit that gets much more use than my various charcoal BBQs.
