Got two of these for my two pups, it was the most affordable and better quality than some other ones I've used before. Of the metal pop-up crates I've used it is probably the simplest/fastest/easiest to set up. Stuck some cardboard below the flooring to stop some of the sound from their paws and covered it with some blankets to get rid of the metal feeling and sounds. My pups love their dens, it makes them feel like they have so much room even if we have the life stages divider up!

Pros: best value, easy set up, durable
Cons: none!
