Cool Texture, Great Product, Notable Cons, Still Recommend
Model: Tab S11/S10 Lite/S10 FE/S9/S9 FE/S8/S7
AMAZING PRODUCT! I've never used a "paper-like" screen protector, but this one applied perfectly and was easy to use! (just follow the instructions!) no bubbles, just one single speck of dust (my own fault - sigh). It creates a very strong "matte" effect and feels cool to run your hand over (very paper-y) CONS: -The fit was SLIGHTLY big for my new S11 tablet, (each corner went RIGHT to the very corner of the tablet ALMOST going over the lip-this was just the corners of the protector and not the edges, which I found weird. IMO, its too close for my own comfort, but it still works none the less, and I've managed to use a case with it too with only minor corner lift). -The texture of the screen protector definitely distorts the pixels slightly, its just something to get used to, and probably something you'd have to see yourself, for if it would bug you or not. -It collects fingerprints like craaazy but they also wipe off craaazy easy too....sooo not fully an issue? just surprised me. Overall, for the money, I still recommend getting this protector if you're at all interested in a "paper-like" finish!

Great quality and easy to apply
Model: iPad A16 11th/10th/Air 11
I love these screen protectors. They feel amazing and they sent an installation kit making the applying process so easy. There was also a squeegee included to make sure air bubbles wouldn’t Be a problem. I’ve had zero problems with the protector reducing the touch sensitivity of the screen, the protectors fit well, seem durable, and are great quality. The price was also reasonable. I’ve never owned other paper-feel screen protectors so I’m not able to give a comparison, but for these being my first ones I am very pleased.

The quality of the screen protector is great, easy to put on without the video. i love how it really feels like writing on paper with my pen especially drawing. I will definitely be buying more for myself,mother and siblings. It’s a good fit for my iPad Air 4th gen and a bang for the buck

Good but Installation was a Bit Iffy
Model: iPad A16 11th/10th/Air 11
90% of the time I use my iPad for school. Originally, I used just a regular screen protector, but it would get dirty with smudges and imprints from my Apple Pencil, and there would be a lot of glare since I'm in a classroom most of the time, which would make it awkward to see what I was writing at times. Plus, the screen protector was too smooth so it would actually be difficult to write legibly. This product makes it a lot easier to write smoother on the iPad. I only just installed it, so I can't say much on the smear protection yet, but I can already see the reduction in glare as well. For $8, getting a pack of two of these with an install kit is a very nice deal imo. My only issue was the installation process, which could've been as much my own fault tbh, but I felt like I aligned the screen protector pretty well with the sticker, however the first time I tried installing it it was way off the center (maybe my case got in the way?). The biggest issue was using the squeegee to pop air bubbles, and this is something they don't mention in neither their instruction guide nor video, but you're supposed to used the velvet red side, not the naked white side: using the white side actually takes the grit off the protector, which is obviously something you don't want on a product that relies on it. Thankfully I have another one in reserve in case this one wears off sooner than expected.

Perfect Paperlike substitute
Model: iPad Air/Pro 13
I’ve been using this screen for roughly two months now and I can say it was so worth it, it is rough on plastic nibs! I am going to order some heavier duty ones and see how it fairs! It works just fine ON TOP of a screen protector isn’t that great! I wanted something like paper like but didn’t want to pay that expensive price for something I wasn’t sure I was going to like. This one does the trick and gives me just enough resistance to feel more in control of my pen! It fits well just make sure to know the size if your screen I had to modify where the camera indent was but it cut just fine and looks great!
