HORRIBLE DESIGN. The double-sided tape only sticks to the top of the bar you're attaching it to, and the way it deviates from the bar doesn't add stability to the controller. I bumped into one of them lightly and it yanked my desk down. I also have a headphone holder on my desk that just attaches to the side with double sided tape and I can't rip it off the desk with a pry bar. Consider other options if you want better quality.
