Used with a hull IQ original Samsung S5 and neat protective shell. The connection is immediate. Heat a little. Getting up and easy one-handed release. Good quality suction cup. Firm support.
But does that hold the load and use GPS is not enough to use GPS + phone. The supplied charger is a 2100 mA and rendering is about 1500 mA. I have not found better in IQ. I will test with a charger 3000 mA.
