I taped this to my desk and let it dry for a few days before even touching it. Failed within an hour or so after the controller was on it. The adhesive still sticks well to my table, but it immediately came off that crappy piece of 3D printed plastic. When I emailed these folks for a replacement, they told me I would have to remove the other one from my desk holding the ultra-light pair of earbuds and send them both back, rather than just sending me a replacement adhesive pad or mount . I also had the opportunity to wait a month for a new "improved" part to be sent from China. I was in no hurry, so I chose this option. Well, like the promise that it could support the controller's weight, it never happened. It's pretty obvious that they know it won't work and they don't mind lying to their customers.
