Tried washing it? :) Water only (no soap or detergent), gently rub with finger to remove any foreign objects, let dry. Some car dash boards have a very pebbly surface and mine just won't stick to them either. Then it goes on the windshield (out of my line of sight, or course).
I only lost suction when the weather was very hot. But I simply wiped the sticky part down with a moist paper towel and it worked again. I also placed mine on top of my dash board, not sure if you placed yours somewhere else like the windshield.
Thank you for your question. Have you attempted to clean the suction cup with warm water and let it air dry? Please feel free to contact tech@bracketron.com, one of our representatives would be happy to help you. Thanks, Bracketron Support
Yes. It's got a big, sticky suction cup. If the dash isn't smooth then it may not attach there, but it'll definitely attach to the windshield, just flip it the other way around.

Thank you for your question! Our suction cup is made from our temporbond technology, which should not leave a mark on the dash. If you have any other questions please feel free to contact tech@bracketron.com and one of our representatives would love to help you! Thank you, Bracketron Support.
It left a bubble from the suction but it went away a few days after I removed it (vinyl dash). It depends on how thick your dash is or whether it is vinyl or another material if it will leave a mark. It did not leave any sticky marks.
