Saco Clear Keyboard Silicon Protector Ultra Thin Cover for 15.6" Acer Nitro 5 AN515-54-54W2, AN515-54-51M5,17.3" Acer Nitro 5 AN517-51,AN715-51 Gaming Laptop - Black with Clear

Finish and fitting of this product is great. Is also waterproof if in case the liquid is spilled on the cover, but if on your laptop or sides of cover then maybe the liquid will find its way and can damage your keyboard but dust will not bother the keyboard.This is definitely for the Acer Nitro 5 and 7 as I'm using it on the 7 series and go for the black keyboard not for transparent one.Also i have uploaded some pics to show the working of keyboard cover in day and night. During day time it is 5/5 stars. But for the text on the keyboard disappears when lights are off and the keyboard light will not penetrate through the texts. Also when the lights are off your have to use the screen brightness to lowest and for this there are 2 pics where the brightness is lowest and 10% ( at 10% the text is somewhat visible on phone camera but not with naked eyes ). Only this is the thing when i find difficult to use keyboard and had to remove the cover or brighten the screen.

Amazing product, it fits perfectly for my Acer pradator hilios 300 (17.3 inch Display). After 3 days of continuous search, I made a right choice.Guys, trust me best product and just 350 Rs. ( Value for money and ur gaming laptop for its pant 😉).Please don't think, just go for it blindly ...One thing is very clear the key travel migh reduce a bit however doesn't take ur gaming experience!

Product does it's purpose like a champFits like a gloveLetters numbers and Signs are printed with high qualityVery thin and super flexibleBut it does block a tad bit of RGB backlight (only con I can come up with )

Everything is good except backlit.

I own Predator Helios 300 and that has a matte metal in its keyboard area, which means the keyboard cover doesn't stay adhered to the keyboard. I work with air cooler blowing air directly at me and the laptop and there is no way this stays in place. It just flies off the keyboard and there is no point in trying to place it in its position multiple times.For that matter, Predator or Nitro series are supposed to be worked on as is, I doubt if there will be any protection available.If you work in an air conditioned room with no fan or air blower, this might work for you. The already mushy keys will feel a little more rubbery and typing experience will be completely damaged.
