Great she’ll!
One of the only shells I could find for this surface, it’s the BEST one. Durable, and quality. No issues at all.

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.

Very durable
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.

it's just ok
I'm glad I found a 'like new' version of this item. it's fine, but I don't really think it's worth the $75 retail price. the kickstand is an issue. it kinda defeats the purpose of a clear case if half of it is covered by a black kickstand. i wish it were clear, but there doesn't seem to be an option for anything like that for the pro x. also it doesn't seem to be very sturdy. trying to pull it out more than a few inches doesn't work it just opens all the way up and falls down. :(

The best
The best case for the Surface Go. Good protection while being pretty light weight. I have had no issues with the stand as others have.

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.

Nice case, but one issue
The packaging is very nice and the case fits very well. I like that it has a clear back on top and bottom, to protect the Surface Pro. What I do not care for is the "Infinity Hinge" on the back. It hold the Surface Pro good for laptop view, but... if you tilt it back so you can write on the screen with pen, it collapses. The hinge is too weak and will not support the tablet when laid back farther. All other cases I have tried do this well, but not this case.
