Alan,
So far my thoughts are thus ... make sure you get it with sod cloth - to close gaps on uneven ground. I love the room. It is very good in the wind ... if the wind is on the back of the shelter. It is easy to set up, very light, you may even feel you do not need a tarp, the shelter is all you need.
The cons are it can be a bit buggy, not as good as a traditional tent in my opinion, but pretty good. If you do not have decent trees, you will need poles or the shelter is a no go.
For me, it is light, packs small, yields good room for me, my packs and my dog. I like it a lot. I find it best to have the screen door pointing away form the lake as most weather comes from the water ... but the best views are in that direction ... tough call sometimes.
It works for me, but is not for everyone I guess. I think I like the room the best ... and sleeping with my old blanket.
Bob.
