I like them.
I purchased both the SUV and the two door, front-back, ruff tough kennels/crates. They seemed to be working out great for my two Miniature American Shepherds. I had originally ordered two SUV crates, but found that they would not fit in the back of my vehicle, side by side. The dogs seem to like them, just like their metal crates. They ride in the new ones at least once a week, sometimes more often. I also like the fact that they can be opened from either side of the opening.
