Now I understand why the original Nintendo Joy-Cons have a flat back. This Joy-Con would be great if you plan to use the elements individually or attach directly to the switch. I notice that no images of these controllers were attached to the Nintendo Joy-Con's grip - that's because the curvature means you can't slide them into your grip. We learned the hard way and then identified the issue by comparing it to our original Nintendo Joy-Con that plugs into the grip.
