In order not to have to always get me the expensive screw cartridges I have later then another "EDELRID piercing cartridge adapter" worried, so can be grilled with the cartridges 1. But of course you could also just put a large 5,10L gas bottle on the floor.
I use Grill-aluminum trays that are custom-fit and then it will save you even complete the cleaning of the grill.
In my opinion, very good value for money. Also there in the field of balcony barbecues anyway hardly selection.
