I installed it using the supplied drywall anchors, and its pretty sturdy into the wall. I love the look and fit is great Quiet and works great. Most of my friends who have a passion for their cars can also attest by Chemical Guys quality. However, it is not great with Google Home if you use music services OTHER Spotify Premium, and you cant add it to a Home speaker group. I inspected the bag and found it to appear very well made of a thick rubber/canvas material. I?m very disappointed in these, and now I will need to order another set somewhere else because the quality is not good enough for me too use for work at home. These mounts are designed for 2 1/2 inch flex tubing. Very Happy with these. I wore them for years before I got rid of them.
