I've had a couple of phone holders over the years and they have invariably let me down. I think most people have experienced them dropping off the windscreen or letting go of the phone and usually just as you're coming up to a roundabout on a busy A road which has six or more exits.
This is a quality product with the suction power of a giant squid tentacle. The build quality is good and the multiple adjustment features enable it to be positioned exactly where you want it with the assurance it's not going to move or wobble.
The phone cradle itself expands with a quick release button on the side and is big enough to hold any phone even if it's in a case like mine is. Plus the same button lets you have your phone back instantly without an ugly struggle.
The bottom section of the cradle is also multi positional so it can support the bottom of your phone but still allow access for a power cable and a jack cable to connect to the car audio system.
It might cost a few more quid than similar products on Amazon but believe me it's worth every penny.
