TapsiRound Double-Sided Adhesive Pads – Made with 3M VHB, 4-Pack (3.15" & 0.91") Sticky Mounting Tape for Phone Holder, Magnetic Mount, GPS on Dashboard & Windshield – Includes Adhesion Promoter

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!

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!

very happy with product..sticks to my truck dash with large phone in verticle position..3m..quality .

Won't stick to 2016 Volvo dash

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.

I got this to hold my cell phone holder in my car after it lost its stickiness. These 3m circles do exactly what I needed them to do. I do not know at this point if they will ruin my dash should I try to remove them, so hopefully not, but I do not plan to try to remove it anytime soon. I recommend them. I did cut it down to size to fit my phone holder but that was easy with scissors. Easy to install, works well, great holding power, in all I am happy with it and the price.

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.

Easy to install, very secure, product as described
