This ultra tough car phone holder clips onto the vent near the stearing wheel in our Volvo XE40 absolutely fine with no flopping around and holds a Samsung S10 perfectly fine with no movement even when going over speed bumps so I couldn't be happier. The arms of the holder are easily adjustable so should fit even very large smartphones with little trouble so this is perfect if you use your satnav a lot in car. Even with a charging cable attached this doesn't make the phone move about so I couldn't be happier highly recommended.####[['tough', 'Product Quality#General', 'positive'], ['recommended', 'Buyer Attitude#Recommendable', 'positive'], ["couldn't be happier", 'Overall#Overall', 'positive']]
