Review on 📱 Enhanced Car Phone Holder, TOLLEFE Secure Grip Hook Air Vent Phone Mount, [Large Phone and Thick Cases Compatible] Car Phone Holder, Supports iPhone 4.0"-7.0" Smartphones by Chris Morales

I bought this to replace a similar mount that only had a cam lever to attach the clip to the air vent. He often slipped. This one has a clamp screw which I thought would provide a more secure fit. Well, it's gotten better, but it still slips sometimes. The clip should be a little longer to reduce this trend. Otherwise I'm satisfied. Good smooth action and good phone grip.
