So im planning to get this over the weekend since the 3DS has such low battery life. i heard it doesnt double the amount of battery life but its similar in a way. i just want to know if u guys like it.
i have updated my 3DS (us) and i updated my acekard 2i. It works perfectly. I had no bricking or glitches. So i think that they just putting the message to scare you.
