Review: Buy This - I tried the only two cases I could find for my 2021 Surface Pro X. The other one constantly turned my device off. This fits my device well.

### ⭐⭐⭐⭐⭐ Buy This
*by A***R on November 13, 2021*

I tried the only two cases I could find for my 2021 Surface Pro X. The other one constantly turned my device off. This fits my device well.

### ⭐⭐⭐⭐⭐ Very durable
*by H***R on January 21, 2025*

Very durable! Easy to install, however it makes plugging accessories in a bit difficult. It also makes it SUPER freaking heavy. But I’d rather it be protected! I’ve already dropped it several times and it has held up perfectly.
