I started using the product effective today. It seems to be stable on the dashboard and does not slide. The cup holder that comes with Garmin keeps falling off and I wanted something that will hold on to the flat surface of the dashboard and reviewed user comments before making the purchase. The price seems to be steep but overall is a good one to keep. I plan to buy another one if the order comes with free shipping. Usually try not to make review comments after purchasing so soon. Will wait for a month to see user experience. Suggest Amazon starts requesting reviews after a month or so or reasonable time like 15 days. My suggestion.
