I have been using the product for almost a year now and often. However, I have not noticed any technical problems with either my Nokia or my Samsung. It also depends on the motorbike and how much it vibrates. In my opinion, however, the anti-vibration module is very useful.
Thank goodness for this community. First of all, thanks to everyone who warned about this. I almost made the same mistake and used it with the iPhone 11. Since the anti-vibration module is not offered here (@Galaxus: Please record immediately!), I'll get it from Louis. Nevertheless, all the components come to a hefty 130.- and I also think the module should be part of the bundle! 10.- would also have been enough
