Its not for me but mybe one day i will need use it, but if it works for you then fine..
I got my male chihuahua @9 months he was crated but he had issues with it lady before me put him in there from 7am until 6pm and came home to a stressed dog and messy crate thats why they "got rid" ..
but after hearing a lot of good reports on it it must be good..
