Having bought a Nintendo 3ds recently, I also decided to purchase a case for it from Amazon. After looking through the options, the best and most appealing was this one which was officially licensed by Nintendo. The price was £5.99 which was pretty reasonable. This case although saying 3DS is also suitable for other versions of the DS (DSi and DS lite specifically) according to its description.
The case itself
The case seems to be manufactured by a company called PowerA whose products are designed and manufactured to the exact specifications of the console. All products they make also meet or exceed Nintendo's standards for quality and safety.
The console does fit exactly into the case but there is not that much extra room at all. The case is black in colour and is made from leather which gives it a stylish look and nice smooth feel. The Nintendo 3DS logo is embossed at the bottom of the case to show it to be an official product. The design also features a Velcro flap closing which is designed to help protect the system. This is pretty good but there are two small gaps at the top of the case after putting the 3DS in. Through these gaps there is the possibility of other things such as water or sharp objects coming through causing damage, so this is something to look out for. There is space for two game cartridges which fit in to their spaces at the front .
This is a pretty good case overall. It is quite stylish and is able to protect the 3DS console and also game cartridges. The small gaps at the top are a slight issue and if you want to store more than two games, you may want to look at other options. For the price and the fact it is an official product , this deserves 4 out of 5 stars overall.
