Poor quality. Estan angostas. 5W in sneakers, but we had to return the 9. In either case, a smooth finish. needed to maybe order an 8. So Ill keep treating it with kid gloves and hope it lasts me for a couple years. Good support (maybe not enough for running), super comfortable, and also SO flattering. Exactly what I had ordered and so far, these bars are holding up perfectly with a roof rack installed on them. I ended up connecting to the charging cable and to my surprise I figured it came with 0% battery charged. Whether or not they look good is of course completely a matter of personal taste.
