Review: good cover access to all ports tough and rugged for sure adds some weight and size - tough case a little bulky but tough. allows the factory keyboard to cover and connect to all ports.
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. Is easy enough to take off and put on to clean as needed, but fits well enough that it will protect my computer. The ports are all easily accessible. I am really happy with this product.

### ⭐⭐⭐⭐⭐ 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.
