I wasn't expecting the suction cup to hold so firmly on my textured dashboard, but it hasn't budged in a week of bumpy commutes. The adjustable arm gives me just the right angle so I can actually see my GPS without craning my neck.

The long arm on this thing is a lifesaver—I can position it so the phone floats right next to the steering wheel without blocking any vents. The suction cup latched onto my textured dash on the first try, and it hasn’t budged even on bumpy roads.

Finally, a mount that actually holds my phone steady on bumpy roads — the long arm gives me the perfect angle without blocking the vents. I've had it for two weeks and the suction hasn't budged once, even on a scorching hot windshield. Even with a thick case, the clip grips tight, which is rare.
