Nine years ago, I purchased a Metropolis Series for a Surface 3, and really liked it. When I needed to buy a Surface Go 4 this summer, I looked for the same/similar design/model for the Go 4. If you use the Surface Go to write with, be warned! There are two major design flaws in the current design of the case. (1) When the kick stand is in its 3rd position (as reclined as it can be), the stand does not lock in place. If you push on the Surface at all, the stand bends further down and then bounces back when you release pressure from the screen. I use the Surface Go to teach from and write on the screen all the time. I need the screen in the 3rd position to get the Surface as flat as I can to write, but still at an angle since I am standing and looking at students while I write. The flex of the stand when any pressure is applied makes the stand not useable for my purpose. I had to resolve to closing the stand and using a textbook to prop/angle the Surface to write on. I did NOT have this problem with the Surface 3 model of the case. (2) The other flaw deals with the thickness of the case where the keyboard attaches. There is too much case/material on that side of the case. When the keyboard is attached AND the kick stand is being used, the keyboard does not lay flat. Over time, I am afraid that this will wear on the flexible part of the keyboard that connects to the Surface. Also, the keyboard can bounce up/down when you type making it harder to type. Given Microsoft has been moving towards keyboards that don't connect at all (Bluetooth) and the Surface Go series not being sold on their website for the general public (Go 4 is a business model), I doubt either of these flaws will get fixed by UGA. However, given this case works for Surface Go 1, 2, 3, and 4, these flaws should have been fixed years ago. I am disappointed in the design. When I need to purchase another tablet and case in the future, I will be more cautious in what case I purchase.
