I purchased this case as a shot in the dark truthfully. I had looked around at 3DS XL cases for almost an hour, then I saw this case in my recommendations. It already looked amazing compared to the others I had viewed because of the astral design, it had the pocket for the charger, the straps to hold the 3DS XL in place, 8 game/SD card holders, and it was very cheap. So I was honestly kind of skeptical, but the case came in about a week ago and I've fallen in love with it!
The build is incredibly sturdy and feels like it was made with quality. Very tough casing. It seems to take absolutely no more room than it needs to to get the job done. It's very slick and takes very little room in a backpack.
*The only thing I do not know for sure here is if your 3DS XL will fit as perfect with a cover/case on it. It fits VERY snug inside the case, and doesn't seem to offer any wiggle room. I would maybe check to see if anyone else has ran into this issue with this style of case, if you plan on keeping a hard shell or something on your 3DS.
