Firstly, if you find the installation to be as easy as shown in the video, I have a bridge in New York that you want to sell. On the plus side, I like the final look after installation (see attached image), but that's purely a matter of taste. Luckily I didn't have to repaint as the color goes well with our freshly painted walls. I can't say anything about the use of glue because I decided to use wall anchors. Just drill two small holes in each piece and screw them to the wall. If I ever need to remove, it's a lot easier to fill, fill and repaint small holes than worry about tearing the existing finish. The instructions say it's not suitable for textured walls, so I took their word for it. I only have one speaker wire so this setup is more than enough for my needs. The downside is that one pack doesn't offer enough mileage, but I have no problem ordering another to get the job done. All in all, take your time and be careful with the installation and the end result will look a lot better than bare wires and I found the quality to be pretty acceptable too.
