It rusts very quickly in four days of a dog show I had rust all over four of my pens that I just bought wasn’t up only four days and it rusted not worth itWe needed to put up temporary fencing and this product was an inexpensive solution. It is sturdy and looks amazing. It is tall enough that my dog is not able to jump over and get out. I would recommend it.I ordered two of the Ultimate ExPens from Precision Pet for the litter of puppies we just had a few weeks ago. It has been really handy for keeping the pups in their "room". We secured the fencing to the walls in our dining room to make a faux wall so they would have plenty of space. It isn't exactly the sturdiest thing, but it definitely works, and we were even able to fold a few panels in that were too long for the room so they have a "fenced" potty area. It works. It's a great size for a few puppies at a time to be in outside, but I wouldn't put all ten puppies in there at once. I don't think it would last! All-in-all, it was a pretty good purchase. The only con would be that it is a little bent out of sorts on some of the panels from shipping.I'm using the gate as a barrier between our kitching/dining area and our living area. We've got one of those open design concept houses and the opening between the kitching/dining area and our living area is about 8 feet. I certainly wasn't going to try using some form of a door gate, the opening is too large. I got this super tall version because my 50lb dog is very athletic and she would've tried to jump over the smaller versions of this. So we installed some hooks on the one side of the opening, and threaded the long pin which holds the pen closed through those hooks to keep the gate tightly attached to the one wall. Against the other wall, we took the extra panels, folded them up against the wall, and stuck a small ottoman next to the wall to keep the gate up. Having the walk-thru door is perfect because we can keep the gate up all the time and use the door to go in and out. I haven't tried it as an enclosed pen, but it works great as a bigger "door gate" for our large opening.I bought this for when we go camping. We have a 30 pound mutt and a 50 pound German Shepard mix. The cage is really tall which I like but it is not very sturdy on its own. With 1 dog in it the cage was knocked over within about 2 minutes. We ended up having to make it a rectangle and stick it between two picnic tables and bungy cord it down. I think it could be better with stakes but we haven't tried that yet so I will have to update after the next camping trip.I purchased the large size because I have two small dogs and wanted them to have room. It was exactly what I had hoped for and works well for what it was intended. So far they have not managed to escape.I selected this brand because I wanted to join them together to house 2 Labradors and a Border/Whippet while camping. I am pleased with the quality of the product. Extremely sturdy and gate is a plus. One of the ExPens was damaged during shipping; however, the vendor responded satisfactorily and shipped a new one. Great purchase!Beautiful in the backyard. Keeps our Dalmatian and cats from wandering with two put together since landlord does not want to fence the yard.
