I have one for deer season and have been seriously considering using it for wildlife photography. I've reached a point in my life where I like shooting pictures of animals more than shooting lead at them.
Edit to add: Pop up blinds are not meant to be left up long term, usually as hunters we would put them up at most for a few days, more to acclimate the animals to it being there than anything else. As a hunter, putting your blinds in an area where they are easily concealed is the key to blending in, along with arriving to the blind well before the animals become active. When we go deer hunting, we usually arrive at the blinds around 4am, the sun rises at 6 this time of year. That gives us 2 hours to get situated before the animals can see us.
I think a cheap one would break-down even faster in that situation. Take a look ar what is called an outhouse blind. They are small, single person blinds that fold flat and take all of 20 seconds to put up and about 60 seconds to put away. They are just big enough for an adult, a seat and your camera bag.
