i have a transparent silicone keyboard cover i've ordered it alongside my swift x so im using it since new, many people complain about the loss of tactile feel on the keys when using this type of cover, since i use it from new, i don't know the difference, but i also suffer from greasy fingers and my keyboard is 100% protected so i cant complain. There's a "Black colored keys" silicon cover version of mine, but the letter/characters are located off center on each key square, rendering the keyboard backlight useless, since the light cannot pass through the key "holes" through the silicon cover letters holes, since they dont align. But sure it can work the rest of the day! https://www.amazon.com/Keyboard-SF314-52-SF314-54-SF314-55-SF514-51/dp/B07MKW5GDJ/ref=sr\_1\_3?crid=2U4IMUIDJQWH0&keywords=acer%2Bswift%2Bkeyboard%2Bcover&qid=1655289893&sprefix=acer%2Bswift%2Bkeybo%2Caps%2C201&sr=8-3&th=1
