Good quality, sounds sometime has a little buzz noise when I open the bottom. 1776 miles in 4 days. I would give this purchase a 5 Star if the appropriate sized earring box had been provided. Comfortable good for running. As I opened the box, I was impressed by how heavy the arms are. The diameter of the grips varies depending on the weight and is fairly large on the 10 and 12 lb. As I tightened the screw that holds the two ends of the bar together, the tack broke off on both sleeves, which did not allow me to be able to tighten the screw all the way. Absolutely loved its so really pretty. Oh and this makes my 7th pair of Keens. i told him they were crocodiles (does anybody really know the difference?), and thats what he has called them since.
