Bought my puppy her first crate at my local petstore...bought the second from Wayfair.  I didnt expect it to be the exact same crate but it was--for substantially less .  Crate is pre-assembled.  You just open it up and hook up the sides.  Has two doors.  Is sturdy metal and fairly light weight (I bought the smallest size for my Pom).  Am very pleased.  Oh, and it also has a plastic tray on the floor to keep things neat under your dogs favorite blanket, pad or bed you put in.
