Review on Cellet Magnetic Air Vent Car Mount: Snap On Technology for Smartphones & Mini Tablets - Universal Compatibility by Kelvin Ward

Looks nice and simple. Easy to assemble, strong magnet holds the phone well. The tilt of the round head does not provide a sufficient angle for positioning and observing the phone's screen when the phone is used for GPS. The sticking metal surface can ONLY be well positioned on a flat surface. Surface that is NOT in my car (most cars I think). THE WORST, it doesn't stick well to the surface. The adhesive is NOT DURABLE and keeps falling off with movement. You won't feel it right away. I was very happy for the first 2-3 days but then it started falling off while driving which was MOST annoying. It was a BIG WASTE OF MONEY. I DO NOT RECOMMEND ANYONE TO BUY IT. TEMPORARY HAPPINESS!
