3M VHB Round Double-Sided Adhesive Pads - 4 Pack of 3.15" and 0.91" Sticky Mounting Tape for Phone Holder, Car Magnetic Mount, GPS Mount on Dashboard and Windshield with Adhesion Promoter

These are perfect. They are the large ones but that's my fault as I did not read the measurements properly. I simply cut the shape out to fit my Mount and on the upside now I have extra material. Very adhesive, works

This phone holder is my star. I’ve had it through 4 cars. I “upgrade” every now and then. But when they brake this one is there in the wings. But the sticking power isn’t as great. I’ve tried several other options but there’s always wiggling from the get go. Now it’s holding tough. I feel confident this will last more than a few weeks

Won't stick to 2016 Volvo dash

Legit 3m products, enough said. These will stay on for years if you prep the surface and follow the easy instructions. Great price and you get a lot for what you pay for. These are super sticky so plan on putting them on carefully because you won't be adjusting them from there.

Great for a variety of uses. I got these pads for a replacement dashcam in my truck. I wanted some new stick pads for the mount, and these have worked out really well. The 3M adhesive is really strong. It adheres well to most surfaces, and it holds tight under a significant amount of weight. It's nice that you get two different sizes, but having 1" and 3.5" sizes seems like an odd combination - why not have a size somewhere in the middle? I've had a few holders with 2" bases that won't work with the smaller size and are dwarfed by the larger pads. Oh well.The “adhesion promoter” is some kind of accelerant for the adhesive, but it smells like acetone and there are multiple warnings to wear gloves when using the wipes. The package says “These products are chemically hazardous, cause great damage to the skin and produce a range of allergic reactions,” so that’s a bit concerning, especially because they are designed like any other alcohol wipe, so there’s a high likelihood that someone would open the package without seeing the warning and potentially irritate their skin or cause an allergic reaction.So the 3M adhesive pads work well, but I’m not going to mess with the “adhesion promoter” wipes, personally.

Stuck my previous dash cam back on to my windshield....it hasn't moved. Used this for other applications as well. Great adhesion!

Perfect and works as described

this sucks
