3M VHB Round Double-Sided Adhesive Pads – 4pcs Each of 8cm and 2.3cm Sticky Mounting Tape for Phone Holder, Car Magnetic Mount on Dashboard and Windshield, with 4 Adhesion Promoter

This works well used to secure a dash can on windscreen and it works very sticky.

This stuff stick so hard it's virtually impossible to remove but you can use release spray if you need to Superb stuff

I’m using it as a replacement adhesion sticker for my Nite Ize Steelie Ball on my dashboard. It’s a little bigger than the actual disc base. I suppose I could’ve trimmed it before using. Been a whole moth.

Stickiness is great. Very easy to use. Great value for money. Appears sturdy once properly prepped.

Very sticky

Good product.

Did not find as adhesive as advertised,

I purchased a dashboard mountable phone holder and the sticky pad supplied simply peeled off. One of these pad stuck it down and two years later it hasn't moved.

This 3M double-sided adhesive is hands down one of the most reliable and versatile products I've used. Whether for mounting small items around the house, securing electronics, or even quick fixes on the go, it performs exceptionally well every time. The bond is incredibly strong and long-lasting. Once it's in place, it holds firm without damaging surfaces when removed properly. I’ve used it on a variety of materials—plastic, metal, glass, and painted walls—and it consistently delivers a clean, strong hold. It's also easy to work with. The backing peels off without hassle, and the adhesive doesn't leave a mess behind. The roll is generous, and a little goes a long way. Whether you're doing crafts, home projects, or DIY fixes, this is a must-have item in your toolkit. Definitely worth the price for the quality and performance. Highly recommended!

pros - needed it for car phone mount and does its job! cons - too many in one pack. I feel that its unnecessary to have so many when I only needed one or two for my uses. I can't speak for others.

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.

These are easy to use and install. I was surprised at how fast the one I used, stuck to my windshield. It was not forgivable if I should have wanted to pull it off and reposition it. So make sure you are clear on where you will place it. I do like how secure the bonding was though.

Item came well packaged, without a lot of wasteful packaging. I appreciate that. Everything was included that I expected. They include some instructions and warning on the “Primer”. More on that later. The sizes are convenient, but I do wish the smaller ones were a 1/5 inch bigger. So my tips on the primer. Read the warnings. This is some toxic stuff. Absolutely do not do what I did and use it indoors. If you do, have a window open and a fan circulating the air. I wore gloves. I ended up having to wrap the little primer pad a few times in plastic and sealed bags to keep the smell away. The smell is overwhelming and absolutely will mess your head up if you don’t dispose of it properly and quickly. It really is powerful and toxic. Take care. I’m happy to find a product that includes single use primer wipes at a reasonable price. I can’t speak to the long term effectiveness of it, but short term use has no issues. Will see how it holds up in the summer sun. I’ll update review later with status. I would recommend these adhesive dots and primer set. Good luck!
