Peslv Privacy Screen for MacBook Pro 16 Inch (2021-2025, M1, M2, M3, M4), MagicSuction™ Removable Anti Spy Black Protector, Glare Blue Light Filter for Mac Laptop Computer

two reflective and has a very low privacy level (very wide viewing angle)

I have 3 devices so I decided to order from this supplier - good price! The product is very nice as what we need 👍 but I have received only 2 pcs 😩 instead of 3 pcs as indicated in the description. 🥲

I originally wanted to protect the screen on my new lenovo thinkpad with a glass protector but they're all glossy and I wanted to keep the anti-glare finish. After some research I decided on this one. The material was thicker and stiffer than I expected, not a film but more like a sheet of hard plastic. This improves protection so I'm pleased. The sizing fit my 14" 16:10 screen perfectly, about 1 mm gap at most between edges. The finish is more matte/dull than the original anti-glare, and further reduces glare. This comes at a cost of slightly reduced text crispness. Pick one: crisp text and glossy/reflective, or softer text and low reflectivity. Screen colour remains rich and beautiful. The product claims to reduce blue light but I don't notice a difference in colour, which is perfect for me. I've attached several photos of the screen taken in a sunny indoor location with the protector attached. You can see some glare on the left side but overall it's pretty minimal for the amount of sun it's receiving. Application Directions and provided stickers for alignment were adequate. Perfect application is always a pain but it's straight-forward. I messed up the first one. I cleaned the screen thoroughly, first with a little dish soap and warm water using a microfibre cloth, then the alcohol pad. I couldn't see any dust so I started applying the screen. Of course about 2/3 of the way through there were several dust bubbles so I aborted and started with a new sheet. The second screen went on almost perfectly. Because the material is stiff it's difficult to maneuver at the end and the application sticker popped off and the last 1/8th of the screen came down before I could squeegee the bubbles. It sticks well so I couldn't lift it back up without risking damaging the finish. I managed to get all but one small bubble out which stubbornly refused to move to the edge of the screen using the squeegee. The next day I worked on it by gently rubbing in circles with my clean dry fingers and it seems to have disappeared. I did this with the screen on for a while to warm up, this might've helped. Be very careful doing this, don't apply much pressure and support the back of the screen with your hand to prevent flex. My advice for application is to place a thin piece of clean plastic (e.g. guitar pick) on the screen edge on opposite side of where you begin to apply the screen. That way if it drops suddenly, there is something to prevent it from closing too early, leaving trapped bubbles. Overall highly recommended if you want extra protection. Remember, there are drawbacks to all screen protectors, and application is finicky so be prepared to use more than one protector to get it right.

Lousy! the magnet isn't strong enough.. the privacy filter keeps dropping! :(

The instruction should be more detailed.
