Tetrax easily attaches to the air vent, it does not obstruct your range of view when driving and it's within your fingertips. Some states are forbidding from mounting any objects, as suction pads for GPS, on the windshield. The complete difference for Tetrax from suction pads may also help to avoid burglary, which can easily recognize the typical signs of the suction pad, suggesting the presence of a GPS inside a vehicle. Tetrax EGO Line is 100 percent metal Tetrax with a rotating ring, which is regulating a pliers system, covered by an anti-abrasion rubber. This light weight (less than 0.6 ounce) reduced volume version, is ergonomic, hard wearing and unalterable over time, thanks to the galvanizing treatment. The six different EGO Line finishes both enhance the invisible attraction system and make this one of the most attractive models currently available on the market.
