Very good Stickyness. Unique material that just keeps it sticky.
However i was not able to put to a good use as yet. I always keep the upper part covered in plastic so dust doesn't settle on it and reduce its stickyness.
Sometimes, it sticks to your stuff so strong that it takes a extra effort to get it out.
I discovered this product when someone was giving me a ride in their car. They had their mint container and hand cream on the mat. I loved the idea. Great at keeping sunglasses on the dash so I can switch back and forth with my regular glasses. Easy to rinse out as it will accumulate dust. For the price it is well worth the purchase. I have not left it out in the hot sun for a summer yet so I plan on changing it's location periodically.
