I have the quick flip 2, the older green one. Sets up quick and works well. Mine has the padded bench seat which I don’t think they have anymore.
The only problem I had with mine was right off the bat I unzipped the front to get out and the door flap swung inward and accross my heater and did a number on the plastic zipper. It will still kinda zip but I now just flip the front up to get in and out.
Look at the way the poles lock together when extended, mine are a little hard to snap back in when putting it away. I think some now are a little easier and have plastic connectors.
The things for me when looking at a new one would be the way the poles lock together, how well and or what is the zipper made of and how does it feel to sit in it.
Hope this helps a little.
