Once it’s together it seems great. I emphasize ONCE IT IS TOGETHER. There were many, many $:,).$,!!@ thrown about putting it up. I really wanted to give it to stars by the end, but it isn’t fair to the quality and use of the product.First off, just so you’re aware, it is extremely heavy. About 75 pounds? So just a heads up for some people.Secondly, the box is stapled with large staples and taped all around. At least mine had tape, which may be because I got the “very good“ condition. You will want to lay it on its side on the floor and open the whole box, because if you try to just pull it out it doesn’t work very well. First cuss word.Once you were able to pull it out, then the fun begins. I suggest reading the instructions first. You may think it’s an easy thing just a pop-up, but please read the first paragraph and see the picture with my cut thumb. Rookie mistake.You have to unhook it from itself to open it up. That was fairly tight. Second cuss word. Now it gets interesting. You pull the sides up but you need to balance it up against some thing like a wall or another solid object. Or have someone hold it. Otherwise, it will collapse upon you.Sounds very simple to just pull up the ends doesn’t it? Not so. Fourth, fifth, sixth, and seventh cuss words. Now the reason I cut my thumb is because I did not read the instructions. Once the end is pulled up, there are hooks on top, and you will want to simply press down on the roof to latch them over. Do not try to just flip them over with your fingers. Your thumb may or may not get caught in between the metal and cause a strain of cuss words. Lesson learned. Another rookie mistake.If you got the one with a divider, this is where you can completely lose your mind. I also suggest you lock your puppy up, if that’s who your kennel is for, in a place it cannot eat the box and try to get in the kennel you are attempting to put together. That’s here nor there.The divider is made of the same metal as the kennel. I wasn’t sure what to expect. Anyway, there are hooks on both sides that you will maneuver inside the kennel and try and hook on the sides. This was the most frustrating part because the hooks would get caught on some of the places it needed to be while the others were catching on other places. This isn’t a simple just pull out and readjust. Because the other side will get caught on the metal squares. At some point, it was diagonally jammed in there and while you try to yank one side to get it out, it’s just a mess of catching on things.What I learned: when trying to connect it close to the end door, I found that the divider hooks would come up on the side door and it seemed the bottom one had no easy way to connect. I decided to move it further back just to avoid this problem. Hook them all on the one side you want, and then go to the other side while keeping tension on the divider, then pull the divider towards you while pushing the side towards the hooks to get them around. Now I know this is just my personal experience, so you may have better luck.It seems like a very solid kennel, and I do like the two doors. Like other reviewer’s, however, the ends of the metal where it is cut is sharp. I think I will try to file them down a little bit. I wish they would have rounded them or filed them down.By the end, I was sweating profusely, apologized to no one at home about my cursing, while at the same time being thankful nobody witness to this process, and then flopped on the couch to immediately write this review. :). Please note that this is an a jovial tone and not sheer anger and disgust at this thing. I do like that you can divide it for smaller puppies.
