With a lot of sense in preparing a good result.

The dismantling of two interlocking spirals twisted in preparation of first use takes time, feeling and skill. A brace is unfortunately broken - 20% loss! The production is to the effect significantly improved.
However, this function results are plain to see. It was not to be seen after sunset no mosquito yet to be felt.
However, one must be able abhaben the smell. After an evening in the atmosphere of the spiral, the clothes smell much after the smoke. It remains to be hoped that the smoke is not harmful. However, because I trust in the German registration rules.
Anyway, you can sit relaxed an evening outdoors.

Addendum:
The product is currently offered very overpriced. We still 11,25EUR paid last week for three packs incl.Shipping! The supplier was the Fa.Fritz Berger and the manufacturer is the Fa.Brunner. As a serious rip off is underway!
