Product review (2 stars): Brackets will not stick
I received the product and read the instructions thoroughly. I cleaned the surface well with alcohol and left overnight to dry. I installed and clamped the product for the precise 20 minutes. I then installed the screw, closed the door and waited several hours before opening the door. The product immediately popped right off of the granite when the door was opened. Very disappointed. This product needs a much better adhesive strip than what it has currently.
