I have owned the older Double Bull, the Grounder 350, grounder 250 and just this past year a Hidden Hunter. While the cost of the HH is twice that of the Grounder as far as quality, ease of setup and take down and its ability to blend in and hold up to snow, the HH is by far the best i've owned. The 350 & 250 I've hunted out of for a couple of years. they are huge but I don't like the window hgt., they fade pretty quickly if left out, cannot handle any snow load at all and if you are moving chasing turkeys they are a pain to breakdown and haul. The older Dbl Bull was nice but since a bear decided I should no longer use mine I have not gone back to them.
