It's not great. I would like one that isn't two sided and is wider. I needed to hold a few scrap pieces together to use a scrap in our bathroom while we decide on what to replace the removed carpet due to a flood. We didn't want to paint the floor as it might encourage mold. Even with anti mold packet added to paint if it's a damp area...prone to water spills at the sink etc. We opted to use some scrap carpet saved to make cat scratch posts out of some day...while we argue over putting in vinyl or ceramic tile or carpet again. Never liked the carpet in the first place...but hey it does make it nice to stand on. This seems to hold the small little pieces we had to fill in around a larger piece for now just fine. Vacuum seems not to yank apart or up either. I did not unstick the other side...left the paper on the exposed side so as not to leave any residue glue on the underlayment.
