This was very easy to put together. It takes a little bit longer to add the wiring around the whole pen and ziptie everything but we were done in an afternoon. We use this for our eight muscovie ducks and they have plenty of room (we ordered the largest size) to eat, sleep, swim and run around when they arent free ranging. We had to buy stakes but the holes were already drilled. Its been a good summertime solution with the ability to winterize in the future. 

One downside is that the tarp will pool water whenever it rains. It could be fixed by affixing a pole on the top to prevent the fencing from dipping down.
