I think because it is higher then the ones that come factory built with the car that is why it makes the noises. $85 for a good mouse! I almost NEVER write reviews but these headphones are wonderful. Only for indoors as they only have the no slip grip on the bottom, but no rubber sole. I mostly charge using a wireless charger anyways so hardly ever have to remove. It was a little expensive in my opinion but it is very high quality. I have many different pairs of fitflop shoes, sandals and boots. Perfetto consiglio acquisto This will work with the Thule T Bolts with a little modification to the hard rubber strip. They are cute but fade very quickly.
