Hi JohnnieG
I've got one of these tents and as a good 3 person 3 season all rounder it's hard to beat. I've used it in heavy rain with 2 other people and it's fast to pitch with the inner staying relatively dry and theres enough room for 3 people and gear inside the tent. The dual entrances mean that if the wind shifts in the night you can always get out of the sheltered side in the morning.
If pitched tight the fly sheds water well although mine leaks a litte around the door but silicone spray solved the problem.
The major downfall of this tent is high wind and a lack of guying points, the guying points it does have are also only on the pole, whereas some to hold the fly away from the inner terra nova style would be useful. I have had it colapse on me in high wind but it springs straight back up again although if your asleep it will wake you up.
so the golden rules are pitch it properly and it'll give you good 3 season use, and no condensation.
