My friend has it and loves it. He likes that he can stand up on his sleeping bag with the door open when he changes at night. Also the storm door can be used as an awning. It's very small packing and very light at 3.5lbs. We've campied in wind with no problems, just be sure to stake it out and use the extra guys. It is a very cool tent.
I don't care for all the stakes it takes to put it up... 6 I think since it has only one pole. If you can't drive the stakes, you'll have to find that many more rocks to guy it out.
It is very waterproof. We've been out in some heavy rain and my friend never had any water problems. On the whole, he loves it.
