Not without its problems when lighting

The Ofenanzünder have in my estimation a serious drawback: they are initially not very easy to ignite. If a corner has caught fire and they are placed in the oven, they go quite like again, because the flame initially only very timidly burns. Almost similar to the flame of a candle.

You have only a couple of times in the kiln burning Wüfel placed and the flame spreads slowly over the surface, they naturally fulfill their purpose and deliver sufficient energy to bring the small logs kindling in transition.

Because these cubes already in the closed space have only moderate Anbrenneigenschaften, I would never use it as a barbecue lighter outside in the open because of the frustration then be programmed for repeatedly erlöschender flame at the slightest breath of air.
