Review on VUP Bike Phone Mount - Detachable Silicone Phone Stand, Rotatable 360°, Face & Touch 🚲 ID Compatible - Universal Mount for iPhone 11/Pro/XS/Max/Xr/X/7/8 Plus, Samsung S10/S9/S8 - Suitable for Bicycles and Motorcycles by Michael Zambrano

Well it's well made, easy to use but useless! I use my phone for geocaching on my bike and need to be able to navigate from my phone. However, the part that holds the real phone has a ferromagnetic element on the back that not only resets my phone's GPS (like ANY PHONE) but also interferes with any location services on the phone. To confirm the problem, I raised my regular compass on the back and indeed it was pulling north straight towards you. So if you only use the phone for listening to music and making calls, this is a great option that feels and lasts well. Spring. If you're trying to navigate, it's a pointless piece of junk.
