First off, the grey PU leather looks SO classy – it instantly upgraded my Surface Book from 'tech gadget' to 'executive chic.' After 3 months of daily use, zero scuffs or color fading.

The detachable design is genius for switching between laptop/tablet mode. Magnetic closure snaps securely but doesn’t interfere with the screen hinge (unlike cheaper cases I’ve tried). Pro tip: The bottom cutout REALLY helps with airflow – my laptop stays noticeably cooler during Zoom marathons.

Minor gripes: The stylus holder fits my Surface Pen snugly, but thicker third-party pens might struggle. Also, while the included keyboard protector is a nice bonus, it does make typing slightly mushier – I removed it for coding sessions.

Final verdict? 9/10. Perfect balance of protection and style for Surface Book owners who actually use their device’s versatility. Just double-check your model like the listing warns – this fits the 13.5" like a glove!
