The instant tent function is absolutely wonderful. Setup and tear down was a breeze. Our family of four had a great time camping this past weekend. We even got some moderate rain shower over the night and we kept nice and dry. 
 
A few suggestions for improvement. 
 
1. Sell full coverage rainfly as an accessory for better insulation - This is a family tent obviously, so versatility would be great. Having a different rainfly that extends to the ground which allows for better insulation would be awesome to switch off between colder and hotter camping conditions. 
 
2. Have Velcro or zipper closure for the vents. Again to improve insulation for the colder nights.
