The controller fits into a bag perfectly, but only rear-side-front (turned 180 degrees comparing to a desk). And since the inlay is glued to the bag and as such cannot be rotated, you have to always rotate the controller to place it into the bag, and rotate it again when placing it on a desk from a bag - and can only access the desk from the front side, like in my case. If you can pick the controller from behind and place it back to a desk from behind, then you won't face the issue.
The other issue is, the foam and polyester (inner material) has some, at least for me, unpleasant smell, so I keep the bag open in a special aired room in hope the smell will be gone after a while.
