I bought this cause I needed a way to move across the country with my bike. I built two already and still have a full container. Ample leg openings. Me encanta y aparte el precio es muy bueno! 5 so ordered the 9-10 size. Would I recommend this D9 unit, the short answer yes, but would advise, do you homework first, ask yourself, what am I expecting this speaker to do, and how do I plan on using it for, and test it. Parts fit together tightly. Ive purchased about a dozen pairs of bluetooth headphones over the years - its been frustrating: Ill find a pair that fits well in my ears, but they dont last long. Surprisingly more global than I had presumed. What screw heads were not stripped, did so easily, but that may have been a sympton of the thread issue.
