So I am posting this review based solely on inspection and assembly. I have not placed my dog in it yet. I will update after the first time in the cage. 2 Stars to start.So first the package did come pretty banged up and the baggy holding the bolts was damaged, luckily it was taped up a lot by UPS I think so nothing fell out. Also no instructions. I mean its intuitive, but took me a few minutes to round up all my sockets and wrenches to determine size.FYI Top bolts are 14MM and bottom bolts are 10MMA lot of the folding "hinges" that had to be tightened were all bent out of shape (see images.) Luckily just the socket and wrench straightened them out upon tightening (was way to easy to bend back during that.) The cage overall does feel incredibly cheap for 180 bucks. I mean the frame is nice and looks good, but seems like they spent a lot of time making the frame and painting it then they did thinking about the wire grids. The grids are THIN metal grids just like the ones on the cheap ones at your local pet store. The grids have a top bar and bottom bar (wire same size) that the vertical grids are attached to. Mind you this top and bottom bar has MICRO tack welds, 3 down the entire run of a 43" length. and the seeds where the horizontal wires are either seemed to the edges or inserted, IDK yet since I did not try to test. You can easily grab the wire and pull in and out and it flexes a LOT. I have 0 faith this will stop my husky from just pulling the panel down. I know the main frame won't budge though lol.Lets move on to the frame itself. Firstly, the wire grids (small holes) in the bottom where the pet stands SUCK. My poor dog walked on ti at first and the wires were between his toes. I rushed him out and moved the plastic mat from under there to in the cage, problem solved. Now this may not be needed for others but my dog hates blankets or crate mats because he overheats. (I would too with that much hair!!) Also the wheels suck. The threads are crooked (no I did not cross thread)The bolts.... ahhh the bots...WHAT A PAIN IN THE A**. Yes I cursed, because thats all you can do. My wrenches were too big to slip into the space, so I had to use an old "included to setup furniture" punched out thin metal one (that fit luckily) to grab the bottom heads. Then used a socket with a knuckle to be able to tighten them. 1/4 turn over and over and over again. The punch metal piece to hold the other bolt really started annoying my hand after the 3rd bolt. Maybe if you had say a 1/4 inch drive socket set, with two drive handles you could make it work better. I did not.Overall I am just not impressed. I should have spent the extra 40 bucks and got the stronger one with steel bars and a much better system. I feel they tried to make this "collapsible" and in dong so made it hard to work. Not to mention, once you fight through and tighten all the bolts, you're not taking it apart, well not easily at least. They should have had the panels bolt into the frame like the top ones did and it would be great! I am going to Zip tie the upper and lower wires to the frame for higher protection because I feel that will little force I could break the tack welds myself and my dogs a million times stronger than me. All it takes is breaking the bottom welds and he can squeeze out even if the sides do stay in place.Overall very disappointed in this. I would honestly return but its such a hassle to put up and take apart I will just keep it and modify as needed, hopefully it works.
