Despite several strong shiver down 1 1/2 weeks, the tent has kept very good - we had very tense the outer tent, so there were no points of contact with the inner tent. Before leaving, I did not impregnated the tent. Although there was morning often condensation on the ceiling of the awning, but I think that was because we have the tent completely closed and only the Beluftungsfenster had open.
The ventilation option at the bottom of the tent, which I've seen in any other Zekt, I rate as very good, as this enstand a pleasant air circulation.
The included lamp with integrated fan are well appreciated. Not only does the Zekt can be brightly lit and well ventilated, but also in the evening playing cards, the lamp has illuminated us more than adequate.
Personally, I like to sleep when camping on an air mattress. However, the length of the tent is relatively low due to the higher lying position. That meant that my feet often hung from the inner tent during the night. My friend who slept on a sleeping pad and therefore was lower than I had the same problems. A completely outstretched Lying was often problematic. We both are great at the 1.80 m. So I would advise all who are even bigger by buying because the limited lying area in the long run can be a real problem.
I would also advise against that tent to use with 3 people. For two people there are (at least in width) enough place to third, I would have felt it to be too narrow.
Basically, I still rate the tent with a 'good' because it has a good quality with many extras at a reasonable price that will remain waterproof even during heavy rain.
