Okay, here are the two bad things I have to say about this cage.1) The wrench that came was the wrong size and it only had a wrench on one end, which was too big.2) The "reinforcement" bar that goes in the middle at the bottom, right below the grated steel flooring is pointless. It doesn't fit into the slot one bit. It just falls off and I don't have any idea why it wasn't welded on like the other ones. That's a big flaw and I hope I don't really need it.3) The top latch is very, very hard to open. I have to use a hammer to get it open and the top doesn't fit right; it's crooked, and I have done everything right to set it up and tighten it correctly. I'll spray some white silicone grease to see if that helps.4) I would not put a large dog in this full time personally like it says the Large is for, because they can't do anything except turn around and you can maybe fit in a bowl. It's big, but it's not big enough for a German Shepherd to walk around and stretch out, in my opinion. But it's okay for shorter times in the cage for transport or an hour here or there, but I wouldn't put a dog in there for 8 hours. Some people do that though, but I just like to give them more room with gates in my hallway when I'm not home if you have that option instead if that's what you're looking for a remedy. Some people don't have that option though.Here are the good things I have to say about this cage.1) It's quality, galvanized metal (not sure if it's steel, but it's nice and heavy so I am assuming it might be). It is made in China though.2) The door locks twice and the top lock (which isn't easy to open because it's crooked and perhaps bent because you can see it's not fitting right) are not easy to open, which is good. I am not putting a dog or cat in here, but a smart creature I am rehabilitating that has the intellect to open latches. So I was happy it will not be able to open the latches easily because it kind of hits a fitting and prohibits it from being slid open easily.3) I like the rollers and the two you put in the front lock so it doesn't roll by itself unless you unlock them.4) I love the flooring because it's not easy for them to get their feet stuck in like many other bottom cages, and the this is the main reason I bought it--for the tray where I have wee wee pads UNDERNEATH the other drawer area with the tray.5) It's solid construction that will last a very long time, for future uses on rescues, too. Overall, I would buy this again.
