Review on 9 Pack Sticky Adhesive Replacement for Socket Mount Base - pop-tech VHB 3M Sticker Pads for Phone Collapsible Grip & Stand Back: 9pcs 35mm Double Sided Tapes & 4pcs Alcohol Prep Pads by Paul Powell

Really looks like they were custom made by 3M to become unsticky after a few weeks. Do yourself a favor and buy 2 chemical epoxies. This is what I want to do next, having gone through about 20 of them before realizing they don't work on purpose. The first pop sockets had a 3M adhesive which extended the life of the phone and then the popsocket company decided to get an adhesive that would fail after a few months and then 3M decided to make a replacement adhesive that would fail after a few months of months. Sounds like a great business plan, but it's a major inconvenience for consumers.
