Im-pec-cable! Solid, practical, discreet. The phone fits comfortably even in MTB Cross Country. The shell protects from bumps (1 Year falls without a single injury). The attachment mechanism is very well designed, easy to install and use (one click to turn the phone, one click to remove it). 2 years of intensive use (multi-day) and I have nothing but positive to share about this Quad Lock.
