I am getting one of these for X-mas, trying to talk the wife into letting me use it early.
I have a 3 person flip over, but it is just too damn heavy to pull by hand. For me this is the perfect run and gun set up, I never use a shelter but like having a seat to fish off of. I can pull this by hand from hole to hole, have all my stuff dry and protected, and be able to sit on my minnow bucket/sit n fish. I imagine setting up tip up will be a breeze too.
I have an Otter Sled, but hated that there wasn't a seat built in and one of the benches that you can order for them is really expensive. I was between this and a FX50 windbreak and liked this better.
