Review on 🚗 Arkon 90mm Adhesive Mounting Disk for Car Dashboards: Compatible with Garmin, TomTom, and other GPS Systems by Paul Dobson

The surface is very smooth, the suction cup holds well. The glue stuck to my dashboard like crazy. Unfortunately the glue didn't stick to the disc itself! There may be some release agent left in the manufacturing process that is preventing proper adhesion. It's hard to tell if this issue affects all blocks or just a small percentage. In the end the adhesive still stuck VERY firmly to my dashboard, the suction cup still stuck firmly to the mounting surface but the factory bond between the disc and the adhesive failed and my phone holder was in the bottom. Let's see how well the warranty claim process works. Will advise.
