Best  doggie residence I have ever had, and I have used a lot of them.  this one earns  top rating for the ease of putting it up and down..  just a click and a twist and it's ready to travel with you without taking up  most of the cargo area.  my chihuahua loves the extra space and  air circulation it allows her.  she naps in  it and spends the night in there.   if there is rain, thunder, or lightning,   She voluntarily escapes  to her favorite place, the crate.  the door on this crate is perfectly balanced so it stays open all the way permitting the dog free access.  it doesn't swing shut and frighten or hurt her.  Also, it locks securely when you want it closed.  wish you made a rate like this even larger for my daughter,s big golden retriever.  I would order it in  a heart beat.  a fine product that serves its purposes well.  thanks.
