Review on 🎧 Optimized Ultra Thin Keyboard Cover for Microsoft Surface Laptop 4 & 3 (2019-2021) - Skin with US Layout, Fits 13.5 & 15 Inch Laptops - Enhances Surface Laptop 4 & 3, Provides Superior Protection & Accessories by Alfred Friedrich

This black keyboard case works great in conditions. However, immediately after unpacking, a design flaw was noticed. The keys are completely blacked out and the characters are colored white, which prevents backlit keys from displaying their characters as originally intended. This is the case if this protection was made for a non-backlit keyboard. The photos in the listing give the false impression that the characters on this cover are translucent on black keys, but that's not the case, and the backlit keyboard becomes useless in a dark environment, like the attached photo on my actual keyboard at night will be shown .
