Review on 🚲 Bike Phone Mount - Stable 360° Rotation Bicycle Phone Holder with 4 Telescopic Arms | Compatible with iPhone & Android (4.5 to 7.2 inches) by Edwin White

_____*Advantages: - Easy to install and remove - Supports both small and extra large phones. .-Portrait-to-landscape rotation is convenient._____*Cons:-When rotating 360 degrees, the locking ring will gradually loosen. You have to re-tighten it every time. I ordered this phone holder for my wife's Trek Marlin 6 and she loves it because she can easily slide her Samsung Galaxy S10e smartphone in and out. The left and right levers to open/open the cage don't require much force, and the middle center button responds to the phone's weight very quickly and firmly clamps the phone's four corners inside. I did the installation for them. and it was a breeze. The phone holder comes with two rubber pads and I ended up using the smaller one on her handlebar. Ball joint rod between the back of the phone holder and the mounting clip on the bike. This design can end up chipping and throwing your phone to the ground - this has happened to me twice and my screen protector cracked once. So I will never use this type of phone holder again. That being said, this Bidakid phone holder has one design flaw: when you rotate your phone from portrait to landscape or vice versa, the locking nut behind the phone holder gradually becomes looser and looser the more you rotate it. Therefore, you must be careful and always tighten it after each turn. Overall, this is a pretty good and solid phone holder priced at $13.99 (as of April 13, 2021). I give 4 stars.
