They were too big for my laptopI haven’t been able to get all of the air bubbles. They don’t affect how touchpad works. It is just irritating. It does fit perfectly.It’s always get out from the mouse area and I have tp press again to keep it. Easy to clean but the adhesive not good qualityIt is a good product but it is almost impossible to get the air bubbles out. I just had to thug it out and leave the bubbles thereI have a budget Chromebook from Samsung that has the worst feeling trackpad on the planet. After failing to find a glass trackpad cover I got one for an MBA thinking it might be a bit oversize but I would trim it with a razor. Turns out the trackpads are very similarly sized and now I have a smoother drag on this POS Chromebook 4 Plus. Install was easy and you get 3 of them.This has been one of the best purchases yet!! Since I use my mouse pad a lot this helps to reduce wear and smooth spots. You should get this for sure.As the title says be prepared to never use your track ever again because of the material they use for this protector. While the sheen definitely matches that of the laptop itself, it causes the cursor on screen to jump corner to corner because the protector interferes with the trackpad’s sensor.First of all, the product is listed as "Clear Anti-Scratch Touchpad Cover Film." However the product is not CLEAR, it's a matte finish which by definition ("dull and flat") is not clear.The product also does not cover the entire trackpad. Its at least 4-5mm smaller than the trackpad on the 2021 (M1 Pro/Max) MBP 16" Trackpad.Easy to install, nice friction, very thin, I recommend.Buena calidad y relación calidad precio.Buena calidad, le queda bien a la Air M1, vienen 2.Recomiendo que lo instalen con paciencia para evitar burbujas.Fácil de poner y buen materialEl precio es un poco elevado para lo que es pero de ahí en fuera todo muy bien.
