It was super easy to assemble, although you have to make sure the center bar is positioned correctly. I had to flip it around so that the pieces aligned correctly and so that it created an overhang on each end. This is the third one I've purchased. I have a girl's club and a boy's club ... no more bunnies please ... and there are more girls than boys. They all love it. I purchased a car cover and use it to cover the run when not in use. My bunnies sleep in their hutch inside at night and I use this run to allow them time for fresh air and frolicking. It was a nice addition to other larger structures I have .... a bunny house. And, if you ask why I have more than a couple of bunnies .... rescued a female that had been dumped, and she was pregnant! Oops! Also want to add that runs are positioned on a concrete patio. Still trying to figure out what works as an accidental bunny parent. These work!

My boyfriend put the run together and he said it's a very cheap product. It was not measured correctly so all the pieces did not matchup. Do not buy this product!

This product was difficult to put together and then started to break and rot after only 6 months. One of the opening top sides broke compleatly off after a year. If you would use this under cover where there's no rain or snow, it would be fine. But if you want it for outdoor and weather conditions, I would not recommenced.
