Fits perfectly. Looks great and it is ""clear""! I bought this because I am planning to add vinyl graphics to my 3dsxl and I did not want them to get damaged; I wanted a hard clear shell so I could still see them through the shell. I have not applied them yet but it is obvious that this shell is going to do exactly what I needed it to do. It's very clear and fits it so well that it does not move around at all. There is absolutely zero wiggle or warpage when attached to the 3dsxl. By that I mean it does not move nor does it have any gap across the main body when pressed down on, it sits perfectly flat against the unit across the top, bottom, and edges.There are also cutouts in all the proper places, Gamecard Slot, Headphone Jack, Stylus (actually makes it easier to find the stylus in the dark if your using the one stored inside the unit, I prefer the larger pen stylus I got free with my awesome Takecase brand storage case), Power Button, 3D Slider, Volume Slider, And External Cameras,I suggest you take your time when applying, I could not get one corner to lock into place and when I started to get frustrated I knew if I tried to force it i would end up cracking it so I took a deep breath, removed the piece (bottom), and re-seated it on the unit and it went on perfectly that time and locked into place.You will hear a clicking sound when the locking ridges engage and you can also see them, so if they are not engaging, do what I did and remove and retry. It is just plastic and it wouldnt shock me if it cracked with not that much force. As I stated above I got it to protect my vinyl graphics more than I did to protect the unit.It will surely protect the outside from getting scratched and may end up cracking if dropped on a hard surface from a few feet but I'd rather have the shell crack which would absorb and defuse that kinetic energy, leaving the unit ending up just fine. That is just my opinion and I am also basing that on dropping a closed 3dsxl or if it landed on a side or corner. It does not cover the rear/hinges area which I actually like because the Z controls would be harder to press if the case surrounded them, this also means the power socket is not blocked by the case as well. If the unit is dropped when open and it lands face down than the shell will offer no extra protection (hopefully you have added glass screen protectors) as it only covers almost all of the outside except the very rear. It also has little nubs on the bottom so when you place the system down then the shell should not be touching the surface of what it is sitting on.Bottom line for the price this is a must buy in my opinion, vinyls or not, they have other colors, but if you have or plan to use vinyls than you really want this case.
