These putty pads are nice and thick, thicker than the major competitor's comparable putty pad product. We use them for improving the acoustic performance of electrical outlets. They are heavy and quite sticky so they work well for this purpose. The only aspect that's a bit difficult with these is that because they're so sticky it can take a bit of effort to get a hold of the edge of the plastic wrapper to peel it off. However, this effort is rewarded because that same stickyness that holds onto the plastic wrapper also makes these stick really well to drywall, electrical outlets, wires, and framing, so the actual installation is a breeze. It's a great produt.
