As the title indicates this is another case of the "bring it all with you" variety. It has storage for the 3DS, 3 games, 2 stylii, charger, and includes a wrist strap. The case is divided into two compartments with the 3DS sliding into a separate sleeve in the first to keep it more secure. The inside of the case is also lined with a soft microfiber, which shouldn't scratch you console.
My gripe with the case is that, in general, it is very large, about 25% wider than the 3DS and about 3 times thicker. It's really quite big. Also, it only has sleeves to carry 3 game cartridges though plenty of space to carry more - Hori makes an optional plastic cartridge carrier that fits the case. Finally, it's outside edges are more flexbile and less padded than the equally large Power A branded case. (Directly comparing the Power A to this case, the Power A case seems to be made of tougher material and is better padded but doesn't carry the charger as easily.)
In summary, this a good case with no glaring flaws, and for those looking to take everything with them, this is a decent choice. For those looking for a sleeker option, I would recommend looking elsewhere.
