The ear part of the frames is very flimsy but that is one purpose. Great flip flop, style, comfort and pricing. Some others are said to last only a year or so before the permanent battery fails and you must buy another entire device (and probably learn how to use it again). I did spray both hangers generously with soapy water. Try saving a little bit more and get a high quality option. If I were to need to fit a wider hub or larger tire the TS-2EXT. El ruido de los botones es agradable y son de calidad. 🙏😇 For my 33" tires on a 16" wheel, that was 2 minutes of hissing before even checking the pressure, then a few more momentary presses to get to the desired deflation. They are classy and such a pretty color.
