Review on Spigen Tempered Protector Designed Case Friendly by John Milligan

You'd better have a clean room with HEPA filters, other HEPA filters when installing this thing, along with nitrile gloves so not a single drop Oil from your hands gets on glue while installing this thing. I would say I was hoping that the way it comes with the plastic shell/case that you put your tablet in looked really nice. Unfortunately, unless you're cleaner than a surgeon, dust, dirt, particles or whatever will stick to the screen before you can put the screen protector on it. Once you peel off the cling film, it becomes like a magnet/black hole, attracting whatever may be floating in the air in your home. You can look at the screen a thousand times before trying to put the protector on, but once you take it off it's like that scene from Avengers Endgame where Doctor Strange opens portals for everyone, except all humans are dust and dirt. In addition, the screen protector is a few millimeters smaller than the screen. So if you don't want it to tilt a bit and cover things like the camera and light sensor, you'll have to lower and raise it a bit. , put it back in, pick it back up, and do it over and over again until you get it right. The problem is that dust, dirt and all fine hairs within 3 blocks are attracted to the adhesive side of the screen. Something will surely get stuck under the screen and it will drive you crazy. It's like being magically teleported under glass. At least it has a little wiper to remove air bubbles that works really well. The problem is, unless you're wearing nitrile or latex gloves, if you get sebum from your hands under the guard and onto the adhesive, it's not an air bubble, it's an oily residue. It doesn't spread with the wiper and stays there until you remove the protective film. You really need to either surgically wash your hands before touching this thing, or better yet, wear nitrile/latex gloves while putting it on. That makes things harder because when the sticky part of the screen touches your gloves, it sticks like crazy, but at least no oil gets on it. Maybe it's just a Spigen thing, but I tried one of their screen protectors for my Nintendo Switch and Pixel 2 XL phone and they did EXACTLY the same thing. Significantly smaller than a sieve, so difficult to align and apply straight, extremely sensitive to sebum that never goes away. Even with Nintendo in particular, if you apply and undo to fix it, a corner of the protector will never stick to the screen again. It's such a shame because Spigen makes really good phone cases and I thought their screen protectors were just as good. No :/ In general, if you have a clean room where you perform surgeries, the ability to cover every millimeter of your body with PPE to prevent foreign particles or dust from entering the area of application, and the placement of the protector magically can fix , first try to stick it on the screen, try it. There's always a chance it's just me -- that I suck at these things, which is always possible, but when it keeps happening, with multiple devices and multiple products, I don't have the slightest feeling that it means it is to blame. .Much luck!
