Extreme Double-Sided Mounting Strips, 8 Strips per Pack | Black Extreme Double-Sided Mounting Strips, 1 in x 3 in, Holds up to 30 lb, MAXIMUM STRENGTH (414H-ST)

been up four days 100 degrees weather still working , will monitor wait and see how long, better than others. UPDATE Fell off fifth day no adherence to wall only on object . Wasted money.

Pros: Works amazingly. Used to mount dashcam on dashboard. Has not come loose like every other 3m I've used. Cons: I found that once I placed it on the mount for my dashcam (without the dashcam mounted) and then stick to the dashboard it felt loose at first. Bbuuttttttt after 24 hours, slid solid as a rock. I'd attach it, place something heavy on it for a couple hours, and then attach whatever.

I'm sure they work great on surfaces that are not slightly textured. They are very very sticky tho. I tried to put my body mirror on my wall that is slightly textured, it held for maybe a few hours.

Extremely strong, I have used this to attach heavy components to the top of cupboards. It holds out even when the environment is very hot outside where most others would say.

Very disappointing. The tape worked for about 20 hours. On the first day, it held my whiteboard securely, so I thought everything was fine. However, on the second day, the tape lost its grip and the whiteboard fell, as shown in the photos. The product claims to hold up to 4.5 kg, but that was not my experience. I would not recommend it.

They hung a mirror in my classroom!

In my quest to find ways to hold up curtain rods without putting holes in the wall I was using command strip holders but the strips would always dry out within a few months and my curtains would end up on the floor. So I decided to try this as the adhesive strip. It’s very difficult to peel off and almost rubbery in texture. I attach it to the wall - peel the other side - place my command hook into it. Let it set overnight and then hang my rods. This is supposed to be heavy duty - weatherproof - well it’s not. At least in my application- within two days the actual plastic command hook was peeling off - of course causing the rod to fall down - there is barely 1 pound of weight on this thin circular suction rod with sheer curtains for a paned window single door- it’s a struggle to get the tape to peel off without affecting the paint but slow and easy it comes off in pieces never the whole piece at once. I noticed that the side the command strip attached to had some bubbles in it. So I reapply a new strip make sure there are no bubbles - wait about a half hour thus time - attach the command fixture - wait another little bit and put the curtains back up. Within 2 days same - wash - rinse - repeat. The command piece had a smooth flat surface so I have no idea why this tape did not work. Very disappointing especially from a name brand. That’s my experience- so that’s my review !! Hope this helps !!

I used this to mount a battery readout on my golf cart. I tried using velcro strips but they wouldn't hold it. This works great

Tried many mounting strips to try to get a board up, and so far these are the winners. easy application and stays so well.

This is supposed to be able to hold 12lbs or something but it couldn’t keep my dashcam stuck to my wind shield. Total disaster

Llevo utilizando este producto ya un tiempo y lo he utilizado para diferentes propósitos y he estado realizando pruebas con el mismo. El producto indica que 1 tira resiste aproximadamente 600 gramos de peso (0.6 Kg), por lo que lo utilice para pegar en una superficie totalmente lisa un multicontacto y unos cargadores pesan mas o menos 400 gramos y hasta ahora lo ha resistido y mantenido muy bien adheridos a esa superficie totalmente lisa. Utilice 4 tiras para hacer una prueba de peso, adherí a una pared totalmente lisa una caja de plástico con paredes totalmente planas y lisas, coloque varios objetos y las 4 tiras resistieron aproximadamente un peso de casi 3 kg. Mi observación, es que este producto es muy bueno para adherirse a la superficie que desees, solo que si es recomendable que sea totalmente lisa y que este previamente limpia, lo intenté en superficies más o menos rugosas pero, no tiene la misma adherencia.

Wow this stuff is strong. I had some little shelves and storage for small bathroom accessories that kept falling with their built in suction caps. This stuff fixed that instantly, it’s super strong. And easy to remove from bathroom tiles too. Exactly what I was looking for.
