Review on Set of 4 Lilware Anti-Slip Sticky Mats - Washable Silicone Gel Pads 📱 for Car Dashboard and Any Surface. Ideal for Phones and Small Items. Color: Black by William Groupp

Contrary to some of the other commenters, I found these pads good for "non-slip" applications but not sticky enough to stick anything to the wall or anything else. than a 45 degree incline. I wanted to use them to attach my phone to the battery but the stick isn't strong enough to hold the two pieces together. Other spacers previously purchased had no problem holding them together. And yes I tried all 4 pads, washed/dried, but they still don't stick.
