Review on Set Of 2 Randconcept 3M VHB Adhesive Dashboard Mounting Disks, 80Mm Diameter For Strong Suction Cup Phone & Garmin GPS Mounting, Compatible With Disks Up To 3.15 Inches Wide by Marc Farrell

The 95mm was really bigger than what I needed but it's good in case I upgrade my GPS in the future. I followed the instructions and cleaned the dash well first. Then, I used the alcohol wipes before applying the disc with the double sided tape. I let it set for a full day before using. Very easy to install and use. I use a few drops of water on the suction cup before I apply it. I've been on some really bumpy roads in my freightliner and the gps hasn't fallen off. It's a 7 inch Garmin dezl.
