With the Seedhouse SL2, I got everything as advertised. Number one, the weight: inlcuding ground cover and minimum stakes (6) this tent is under 4 lbs. Number two, is size. This is a two-person tent. I found it spacious for one person, but only slightly cramped for two. Nice vestibule size. I mean it's not big enough for a backpack, but there's plenty of room for boots, and then some--space for keeping boots dryer when it rains sideways.
Setup is better than the one-person version. The one-person relies on stakes to open up the foot of the tent, requiring an extra two stakes to setup. And, the one-person weight is *not* as advertised. I found only a 5-ounce difference between the one and two person models. Definitley not worth the loss of space and more difficult setup in my book.
The tent performed very well under adverse conditions. The factory-seam-sealing kept everything dry inside during a three-hour down-pour, and the tent was solid during windy conditions (gusts to 30 and several guy-out points I hadn't used yet).
Although the tent is well-ventilated (being an all mesh body), I did not find it too drafty (due to a well-engineered rain fly).
After ten years and having lead over 50 backpack trips, and having owned seven other backpacking tents (including Sierra Designs, Marmot, REI and Eureka) I reccomend this as the best 3-season, 2-man backpacking tent I have seen yet.
