egrips EG-30P-CL-S Clear Anti-Slip Kit - Universal Grip Stickers for Mobile Cell Phone, Remotes, Handheld Devices, etc - Strong Adhesive - Flat Surfaces Only - Not for Phone Sides, 30 Piece

I use this for my cell phone. The grips prevent falls from the table, counters, arm rests, etc. The grips last a good amount of time. I tried a similar product, but it did not stand up to the quality of e-grips.

I chose to stick them on the underside of the latrine seat lid. Whether it’s an older or new lid cover they generally are not suitable places to sit on when closed, as they glide across the porcelain surface to easily. I found that just two on either underside where the rim meets the porcelain helps stay in place; this would include when I reach for something or lean to either side, it stays put. I’m very pleased with it. I would suggest that the surface (if it’s smooth like the application describes) be cleaned with isopropyl alcohol and scuffed up a tad to help it bond better and not peel off.

I have neuropathy in my hands & I drop everything. These grips are one of the few things that help me hold on to my phone, ecigs, remotes, everything. They feel like rubber, other brands don't. They say not to but I have them wrapped around the edge on my LG stylo4 & so far so good. I will let you know if they stay. (They did not stay wrapped around, after a few days they started to peel, but only where I wrapped them. I was able to cut them straight & they are fine now). I suppose that is why they tell you not to do it. It takes most of the package to cover a phone the way that I need it, because of my neuropathy so if you have a big job get two packs. One packet will cover a tablet or a big phone but not much more. Expensive I think, but maybe not when you think about it. And let me tell you when I peeled up the edge to trim it in a straight line it was on there good but didn't leave adhesive on my phone. Very pleased.

I tested these out back when I had the world's most slippery phone (the moto x4) and loved them so much I used them on the pixel 3. I now have a replacement pixel 3 and need to buy more. But that's okay--take my money--these things are bloody fantastic. I can rest my phone on any surface and nearly any angle (hello silky boppy pillow) and it stays. But they're not sticky to the touch--they're just ... grippy. My phone also stays in my back pocket way better. I can hold my phone with one hand (one finger if necessary). They adhere well to the phone and last a long time (they will eventually rub down to nothing, but it takes years. They definitely die a good death.). They stick well to every phone I've owned (though not to really rounded edges). The only caveat is one corners of one of the square stickies got snagged and came unstuck, so it might be worth it to cut down the square corners into rounded corners before attaching those. Still. Black magic. It's wonderful.

These do exactly what they are supposed to do. They add grip to slippery hard smart phone cases. And this is the only brand that really works. That said, they do not last forever. They will eventually start to come off at the edges, especially if you are hard on your phone (kids). This is one of the reasons I only gave three stars for the value. The other reason is that each pack only has a few of the shapes that are most useful on smart phone cases, which means that you have to keep buying more sets of them. I have to believe this is intentional on the part of the manufacturer--a dirty little trick to force you to spend more money.
