I gave it 2-stars as I intended for it to be a cheap rug - being used under our dog crates. It's very durable, easy to clean; however, it smells of glue! It had a pretty strong odor about 4 weeks ago - has since aired out a bit, but still a sent. Not sure if it is odor eliminating in any capacity other than the ability to drown out other odors! Would not purchase again.
