We put our garmin gps units in the dash, over the speedometer area. Adhesion is great and came with a few different size knobs. It is small in size but easy to tighten to car ac vent by the simple knob. Keeps the garmin on the truck's windshield.

All the components are sufficiently sturdy that i had no concerns about long-term reliability. It's very sturdy and holds the camera steady!

The wingnuts are too small to be easily hand-tightened. The whole mess falls apart as you loosen it. There were no parts to attach it and inadequate instructions.

Picture is deceiving. This item is not as advertised. Instead, invest in a ram brand gps mount.

Spend the money and get a real garmin mount, and save the headaches. These suction cups tends to lose suction due to cracks in rubber, and navigator falls off glass.
