Review on X-Grip Phone Mount with Twist-Lock Suction Base & Short Arm for Vehicle Windshields - RAM Mounts RAP-B-166-2-A-UN7U by Peter Parks

I love that the suction cup works every time and never falls off like inferior devices. You actually rotate the base to create suction on the glass. This company manufactures equipment for police cars, etc. and shows the quality. I like to buy once and forget and don't fill the bin with inferior versions of the product. I recommend anyone looking for a phone or GPS holder to invest in this and get on with it. You can even replace parts if your vehicle needs replacing! I like that I can order a spare if something goes wrong. As a harsh critic of how it works, I don't see that with this product. Made in USA is a definite plus.
