Crutchfield Customer Review (What's this?)
I mounted the Magic Mount to the left side of my windshield to allow the use of my phone as a GPS, and I've consistently been disappointed with the product. The mount itself is spectacular; the long neck makes it very flexible and puts the phone in a perfect position. However, the magnetic holding mechanism fails to hold my phone reliably. I have a Samsung J3 with a relatively slim case, so it's not a particularly heavy phone, and I have the magnetic plate attached to my phone under the case. If I take the time to carefully position it on the mount so it lines up perfectly it's more likely to stay, but the whole thing is a headache. And forget about charging your phone in the mount, the extra stress from the cable makes it impossible for the phone to stay mounted even when using the cable retention clip on the mount to take the worst of the weight off of the phone.
Pros: Flexible mount, versatile
Cons: Phone won't stay in place
