The mechanisms became stiff very quickly and now one of the straps has so many worn down teeth on one side that I need to bring blocking at all times in case the thickness of what Im strapping down falls on that part of the wheel, as it simply wont hold there anymore. Apart from the frustrating noise, it seems like a good product. I cannot see these aging as gracefully as those and I suppose my only complaint is they do not fit my taste in appearance, as I had hoped they would. So, 3 stars. I ordered my regular size of 7M. Anyways I obviously recommend. IT WILL NOT RUN IN THE BACKGROUND. The shoe tore after 6 weeks of use on the fabric by the small toe. That being said, Im a bit disappointed with the hook length and extension. The clip on the side gives the case great versatility to clip onto a purse or belt buckle.
