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 Mark Perry

First off these were delivered to the wrong house and we had to go searching for them. This product works as described. Mine had a thicker glue resin on one side so after attaching to a level surface I noticed the back looked like it was lifting, but it’s not. I was able to use it within 4 hours of installing. Keeps my phone off the window and out of my windshield site plan. I have an older model phone holder and this works great!
