Unlike the other reviewer, I had no problem with the assembly of this crate. I had it put together within 5 minutes and it's perfect - holes all matched up, etc.
This is the airline-approved type of crate which is made of a very durable plastic, It came with 2 water/food bowls which attach to the door.
If using this for airline travel, of course, this size crate will go into the cargo area, it should only be used for larger dogs, you don't want too much space or there could be a lot of jossling around during turbulence. If you are using this for crating overnight at home, this would not be for a large dog. In fact, if you stuffed a large German Shepherd sized dog in this for overnight crating, that would be darn cruel, the poor dog wouldn't have room to stand up or turn around. If home crating either overnight or while at work, I wouldn't put a dog much larger than 20 lbs. in this crate.
I use it for overnight crating of my dog, it's her den/cave - I prefer this type crate to the wire see-through type for this very reason. Dogs like their dens. My dog doesn't think it's torture at all to go in this at night, and she gets a good night's sleep and doesn't have to worry about a cat jumping on her just for meanness.
It's easy to clean too, I just pull it outdoors to the patio and hose it. Petmate also makes mats that fit inside perfectly.
WARNING: There is one thing you have to be concerned about when crating your dog. Make sure your dog's collar and/or tags can't get caught in any openings or the door of the crate, especially if it's a small dog. It might be a freak accident, but a small dog that is jumping around could possibly hang itself if the collar or tags would happen to "catch" on something.
