different ones, can't recall the brands right now but here is what I found. On one that pops open and sets up fairly easily , the spring steel inside the canvas twisted the wrong upon trying to close it back up and to this day the thing will not go back into it's little carrying bag. When open, it must be staked down or the least little breeze will knock it over. It is otherwise nice to hunt from unless you plan to bow hunt. It is not large enough not to catch the broadhead on the canvas in front of your seat.
The second one uses a shock corded pole set up and goes up fairly quickly. It is very nice, except the zip open windows are set so low, you must almost sit on the ground to see out of them. The frame work is a bit too tall to see over the top of the frame and shoot that way, so you must modify a chair of some type or sit on the ground. It does fit two people rather snugly and doesn't take much time to setup or take down. I don't use either of these blinds very often, but have and will use them again in the right situation.
