We’ve had this wall paper up for 2 months now, and it’s holding up fine. The 3rd drop that we used no longer matched the pattern repeat about halfway down the wall (see photo) it’s in a corner and almost hidden by the mirror and vanity. 

The installation process was fairly easy, but I highly recommend having 2 people. We weren’t sure how much water to spray on the back and had to re-spray the edges to keep them down. I also used clear silicone around the wall edges to ensure it doesn’t lift in the figure.
