I have one. What exactly did you want to know?
I have the 1 man model. It is ultra light, and very easy to carry. you can kinda hang it from stuff but you need to be extra cautious when pitching it in windy areas. The lack of a floor can be a pain and a blessing depending on where you are. The fact that you need a pole to pitch it seems like no big deal but the last time I used mine it was around the Suffield area(no trees)
If you want ultra light I would reccomend it but otherwise you can do just as good for less money with some of the other one man shelters.
If ultra lite is your game I have also used this and found it just as good for a lot less money.
