Ill update on durability after a month or 2. It has the Android 9. All this is just minor things. Best investment! This mount is basically 2 identical parts attached to each other so they can rotate to accommodate a 90 degree offset flashlight that sits parallel to your bike handle bars or it can rotate 90 degrees to use a more common straight flashlight that sits perpendicular to your handlebars. I have seen reviews were people claim that the device made no difference and the volume was too low. I may buy another pair in another color! Súper práctico, se monta solo, no pesa nada y ocupa poco espacio con muy buena capacidad de almacenamiento. It?s more heavy duty than expected. This is a very good product and I highly recommend it.
