I've already used over two weekends (4 nights). On the first weekend, the nights were a bit cool (10 - 12 ° C). With a thicker sleeping bag that is certainly no problem. Only the air condenses inside the tent.
On the second weekend it rained for several hours even more. The interior remained dry.
The building is a breeze. With one or two times practicing the folding is also not a big deal. At the processing me anything negative noticed. The zippers work without difficulties.
The interior is enough good for a 1.80m tall person plus some luggage and air mattress. If you like it more closely, you can sleep in it also determined for two.
