I used the Litetrek III in Patagonia with my girlfriend for about a month We were in campsites mostly plus a couple of days up in the mountains.
It's really quick to put up, had enough space to store our stuff inside, is reasonably light and relatively cheap. Orientated away from the wind and with the guy lines up it withstood some strong winds and kept us dry in some big storms.
The downsides are that it's obviously not a 4 season tent. When camping up in mountains it was colder and more buffeted by the wind when compared to some of the 4 season tents next to us.
I wouldn't describe it as bomb proof but we didn't have any problems or breakages on our trip. For our needs we thought that it was a good compromise between weight and robustness.
