As a result of using this suction mount I found that my GPS was easily mounted on my dashboard without any hassle .The mount is very stable, even on bumpy roads, and holds the GPS securely without any slipping or wobbling. The mount doesn`t cause any interference with the electronics in the car, so I can focus on driving without any distractions. The only downside is that the suction can be difficult to remove from the dashboard, but overall, it's a great product..See full review
