The phone side of the device holds the phone adequately. Gooseneck is stiff, but bendy enough to mould into place.
Suction cup, um, sucks. In the negative sense. I tried softening it under hot water, which did help somewhat. However, the lever that controls the suction is (a) small and fiddly, and (b) offers a lot of resistance. And now it's broken.
Since it was less than the cost of a pint, I'm not bothered, but it's still an unpleasant feeling when a product doesn't live up to the most basic of expectations.
