I own a Laserlarge 1 and would strongly recommend it.
The first weekend I used the tent it was very wet and windy and I was worried about how the Laserlarge would cope. The wind was so strong that weekend that it flattened a number of tents forcing people to pack up and leave, but I had no such problems with the Laserlarge which proved itself to be both stable and waterproof in testing conditions.
Since buying the Laserlarge I have spent about ten nights camping out in it and cannot fault it. The only thing I didn't like was the tent pegs that Terra Nova supplied with the tent, but they are easy to replace.
Despite its light weight the tent is very roomy, I especially like the generous sized porch. I have cut the groundsheet of an old tent to fit the inside dimensions of the porch, it adds an extra 130gms onto the weight of the tent but allows me to use the porch as a living area :)
