Just used this tent this weekend, very easy to set up, only three poles. Not tested the waterproofness of this tent as the weather has been dry. Neighbours at the campsite were impressed in the speed we built it, I never timed it but 10 minutes as a rough guess.
Great tent with the groundsheet being fully integrated so no cold drafts.
Plenty of space for 2 adults and 2 10 yr old boys and a small dog for a weekend, we are looking at buying the extension for longer trips.
