Is Auerhahn was to be expected, super quality, impeccable finish, just perfect. I am absolutely delighted. What I would hope by Auerhahn, a suitable cover so that they can leave outside even in the rain. While it is no rainwater in the tank for the bioethanol as a super seal is present. However, outside of the discs is then in the tank, the water can not drain. Consumption of bioethanol is Allerding quite high, but it makes up a unique fire game.
